BarChart(), Histogram(),
Plot() for facet plots: Axis tick lengths are now smaller,
to match the lengths for non-facet Plot()
visualizations.
Plot(): Parameter lwd renamed
line_width. Parameter ts_PIlevel renamed
ts_PI.
PieChart(): Parameter lwd renamed
line_width. Parameter lty renamed
line_type.
Plot(): To jitter either axis coordinate, set to a
specific value of jitter_x and/or jitter_y or
have the value set by Plot(), indicated by setting the
corresponding jitter parameter to NULL. Applying jitter to
both the x-axis and y-axis was by design
occurring by default for all analyses, probably too aggressive. Now, the
default values for a scatterplot of continuous variables is 0. For
discrete variables or a VBS plot (violin-box-scatter plot), different
formulas provide default jitter values greater than 0, easily overridden
by providing specific values.
Plot(): For non-linear values of parameter
fit, now provide the MSE of the model fit to the original,
non-linear data. Can compare this MSE to that of the linear model by
running another analysis, setting fit to
"lm".
Plot(): New parameter fit_new to
provide values of the x-variable from which to compute
(predict) values of the y-variable for linear and
non-linear forms specified by the fit parameter, except for
"loess".
Plot(): As with origin_y from the
previous lessR version, the default value of
origin_x favors 0 if there is not too much resulting blank
space in the corresponding visualization. Or, manually specify the
desired parameter value.
Plot(): For Trellis (facet) plots, axis values in
the even hundred thousands are now expressed in K notation,
such as 100K instead of 100000, a feature previously added to non-facet
plots.
Regression(): The criteria for plotting points as
bubbles for a single predictor model was deemed too encompassing. The
new criteria are to plot as bubbles by default only when the single
predictive variable and the target variable have less than or equal to
12 unique values. Boolean parameter bubble_plot added to
override default for displaying the scatterplot of the one predictor
variable with the target variable as a bubble plot.
Regression(): Parameter size added to
override default for the size of plotted points.
Histogram(): Axis labels were written too far from the
corresponding tick marks.
Plot(): A one-variable categorical variable coded as a
factor can now be plotted as a bubble plot. If the categorical variable
is numerical, add a value of the radius parameter to force
as a bubble plot instead of a VBS plot.
style(): Transparency now properly recognized with
add_fill colors with specified transparency from
add_trans parameter.
style(): Default fill for a superimposed rectangle on a
visualization with style(add="rect") changed to light gray
with light transparency to allow content within the rectangle to be
viewed, "#D9D9D920".
Plot(): New parameter ts_method to specify
the estimation method for generating a forecast. The default is
"es" for exponential smoothing, the only available previous
method. Can now also implement "lm" for least squares
linear regression model with seasonality, which de-seasonalizes the data
and then adds seasonality back to the estimated regression line.Plot(): To generalize parameter names for multiple
estimation methods, all parameters that began with time_
and es_ now begin with ts_. For example,
time_unit is now ts_unit, and
es_seasons becomes ts_seasons.
Plot(): New parameter value days7 for
ts_unit. All other time units are based on the 365 or 366
day year, the interval over which seasons are assessed. Seasonality for
days is not generally meaningful assessed over the entire
year but can be for days of the week. The time unit of
days7 assesses seasonality of days over the 7-day week,
such as, for example, more sales on Monday than on Sunday.
Plot(): New parameter origin_y to set
the minimum value of the y axis, though the data will not
be truncated if the value is larger than the smallest y
value, instead triggering an error. This parameter compliments existing
parameters origin_x, and also scale_y, which
sets the minimum, maximum, and interval for scaling the y
axis. Its value is set to 0 by default in relevant situations.
Plot(): New parameter ts_NA to specify
treatment of missing values for the y-variable. By default,
y missing values, those with value NA, do not
plot, leaving a blank space. Or, specify a value such as 0 to replace
the NA to plot that y-value for the
corresponding date on the x-axis.
STL(): Output data structure provided that consists
of four variables: date according to the named date variable and the
extracted trend, season, and error components. Example: s <- STL(Qtr,
Sales) outputs to the data frame s.
pivot(): When computing a cross-tab table, if the
first variable was a factor the analysis would crash. Now
fixed.
Plot(): When plotting a time series, x-axis tic
lengths and the margin for value labels is refined.
Plot(): Refined the extraction of the date variable
and the y variable from a time series used in internal
processing, such as identifying leap years to provide more generally
accurate dates.
Plot(): When plotting a time series with multiple
y values, the y-axis label now properly
displays.
Plot(): When plotting a stacked time series, the
vertical legend now displays with the proper colors and in the same
order as the display of the stacked variables.
Plot(): If plotting daily data with a time unit of
"weeks", then dates are plotted as individual dates by days
instead of months.
Plot(): If plotting a y categorical
variable and an x continuous variable, the number of
decimal digits for the displayed statistics is now based on the decimal
digits inherent in the continuous variable instead of set at 1.
Plot(): For a time series exponential smoothing
forecast, now display SSE and MSE fit indices, the linear trend and
seasonal coefficients, and the obtained smoothing parameter
values.
Plot(): Improved conversion of character string
numeric dates to R type Date.
Plot(): Read dates entered as character strings
formatted as:
Plot(): Forecasting output now written to an output
list object such as p <- Plot(...) with names out_frcst,
out_fitted, out_coefs, and out_params. This output is accessible for
showing just part of the output, such as p$out_frcst when
writing R Markdown documents from the results.
STL(): Set parameter show_range to
TRUE to show the range of each component. Before
TRUE was the default.
STL(): Parameter quiet added to
suppress text output and parameter do_plot added to
suppress the visualization.
Plot(): Exponential smoothing of multiplicative
models now working, indicated by
es_type="multiplicative".
Plot(): Can set style(suggest=FALSE)
for a time series plot.
Plot(): If missing data for a run chart, a proper
error message is now displayed if attempting to show the runs, for which
missing data does not work.
Plot(): Turn off the plot with
do_plot=FALSE, leaving only text output, now
works.
Plot(): If plotting a run chart with multiple
y variables, adjacent points are now connected with line
segments for each of the y variables. Example:
Plot(.Index, c(y1,y2,y3)).
Plot(): Exponential smoothing forecasting
implemented with accompanying visualization. New parameters include
time_ahead for the number of time_units to
forecast into the future, and time_format to provide a
specific format for the date variable if not detected correctly by
default. Control aspects of the exponential smoothing estimation and
prediction algorithms with parameters es_level (alpha),
es_trend (beta), es_seasons (gamma),
es_type for additive or multiplicative seasonality, and
es_PIlevel for the level of the prediction
intervals.
Plot(): Character string versions of a date as in a
variety of forms as digits, such as “08/18/2024”, are now by default
converted to variable type of Date. However, this
conversion is inherently ambiguous, so the time_format
parameter is provided as a means to provide the precise format if
needed, including other formats such as “August 18, 2024”. Also, a
sequence of four-digit integers within the usual range of dates will
also convert automatically to a variable of type `Dates.
STL(): A wrapper for Base R stl() that
provides additional information and utility:
Date as the x-variable and the time series
values as the y-variable instead of an R time series.Date.BarChart(), Histogram(),
Plot(): If the x- or y- axis
values in the resulting plots all end in 000, then the 000 is replaced
with a K, such as 120000 plotted as an axis value of
120K.
LineChart(): Deprecated for years, now removed as
its functionality has been incorporated into Plot() and
extended with the x-variable of type
Date.
Plot(): Parameter run dropped. Instead,
to maintain the position of the variable of interest to be plotted, as
the y-variable, indicate a run chart by specifying
.Index as the x-variable, that is, the first
variable listed. That name, beginning with a period, .,
indicates data values for the variable Will be created
automatically.
Plot(): Increase the default size of the dot in the
Cleveland dot plot and related.
Plot(): When parameter time_unit is
explicitly set, proper dates are now displayed on the x-axis when there
is a by variable.
Plot(): Suggestions are working. To turn off:
style(suggest=FALSE).
BarChart(), Histogram(),
Plot(): Parameter names by1 and, where
applicable, by2, deprecated, replaced with more descriptive
new names facet1 and facet2.
Plot(): Using functions from the xts package, when
plotting a time series dates are now formatted according to their
natural unit. For example, when plotting by years, just years are listed
without the month and the day.
Plot(): When plotting a times series and requesting
a level of time aggregation with the time_unit parameter
that is more detailed than the available data, the analysis
appropriately terminates with an error message. For example, if the time
series data is monthly and an aggregation of weeks is
requested, no analysis is done.
Plot(): For plotting time series data, new parameter
n_date_ticks added to override the default number of ticks
on the x axis, the date axis.
Plot(): For Trellis (facet or lattice) plots of bar
charts and histograms, each panel is labeled with the proper size of
text in the corresponding panel strip.vignettes: These extensive examples are moved to the
web to save space as the installed lessR was exceeding the accepted
maximum limit. The web address is given from
library(lessR).
BarChart(): When doing a composite plot, if calling
fill=getColors(...) for a divergent palette, such as for
one bar for all items on an attitude survey, no longer need to
explicitly add n= for the number of levels.
getColors(): Added three pre-defined palettes from
the colorpace package: rainbow_hcl,
terrain_hcl, and heat_hcl, e.g.,
getColors("rainbow_hcl").
getColors(): Adjusted the margins to better fit the
plot window when the color wheel or rectangle is displayed.
getColors(): Default Tableau qualitative palette
added as a name to recognize and translate to the colors, also for
visualization functions, such as fill="Tableau".
Plot(): New parameter time_unit for
when the x-variable is a Date variable and a time series is
plotted with automatic aggregation of the time unit according to the
specified value, such as "years" plotted from daily
dates.
Plot(): New parameter time_agg for when
the x-variable is a Date variable and a time series is
plotted with automatic aggregation to specify the type of aggregation
with "sum" the default.
Plot(): Pearson correlation analysis no longer
displayed if the x-variable is a date, that is, if a time series is
plotted.
all visualizations: Grid lines not affected in some
plots that would add some unintended transparency to the
visualizations.
PieChart(): User now warned that the
values family of parameters is changed to
labels, though the old reference still will work.
Read(): If quiet=TRUE, automatically
modified variable names to legal R names are not reported.
all visualizations: Default colors softened a bit
with default transparency level moved from 0 to
0.10.
ANOVA(), BarChart(),
Histogram(), PieChart(), pivot(),
Plot(), Regression(), ttest():

PieChart(), Plot(): Parameter
filter (formerly rows), now reports the number
of rows of data before and after the filtering along with the logical
statement that defines the filter.

systems.
BarChart(): values_digits now
labels_decimals though old value still works.

input, default decimal digits is now 2, which can be
customized with labels_digits.
BarChart(): Default labels (formerly
values) that are labeled on each bar now set at
input except when aggregating counts, where it remains at
%.
Plot(): Parameter area_fill on time
series plots now extends down to the level of the y-variable specified
with scale_y instead of the minimum value of y.
Plot(): Binning large data sets now results in
larger bubbles.
dataStockPrice: Data table updated with stock prices
through May 2024, and trading volume added as the fourth
variable.

variables except those specified as the group, response, or ID are
deleted as their values are not evenly distributed over the new wide
format variables.
pivot(): Fixed a bug on the output. The results were
correct but not formatted correctly.BarChart(): Parameter stat_x added to
specify how to plot the y-axis if there is no
y variable specified, with default value of

%. These values are separated from the stat
parameter which now exclusively pertains to the transformation of a
specified y numerical variable.
BarChart(), Histogram(),
Plot(): Parameters lab_adj,
margin_adj, and legend_adj renamed for clarity
to lab_adjust, margin_adjust, and
legend_adjust.

multiple groups according to parameter by returns to
"circle" with the new shape value
"vary" if desired to retain a sequence of default shapes
across the different groups.

the values that it can analyze such as lm, so no longer can
be set to TRUE or FALSE.
Read() and Write(): Support the modern,
fast, and efficient data file formats from the arrow
package, feather and parquet.

"mean".
Plot(): If a time series is plotted from a x-axis
variable that is not of type Date, then, setting
segments=TRUE connects the points (which can vanish if
size=0), but the line width parameter lwd was
previously not responsive in this context.
Logit(), Regression(): For categorical predictor
variables, the conversion to indicator variables now happens before the
analysis. All analyses are now only of numeric variables so that the
correlation matrix, scatterplot matrix, tolerance, and best subset
analyses are now conducted for categorical predictor variables.

name of the aggregated variable concatenated with an underscore and the
name of the operation.
Plot(): For plots of two or more variables, the
right-margin legend is displayed with a smaller font size and centered
more effectively.
prob_norm(): Function terminates if value of
lo is greater than hi instead of returning a
meaningless result.
getColors(): Default for parameter
output is TRUE only for a direct call from the
console. If embedded in a function call such as for the
fill parameter, or even if directly called in R Markdown,
then set output=TRUE to view the calculated.
palette

if the assigned name for a single variable analysis contains the name of
the variable analyzed from the input data frame.
Plot(): For stacked time series plots, default for
size of points is now 0.
Plot(): For lattice plots, if there is only a single
point to plot in a panel, just the point is plotted instead of also
attempting to plot a violin and a box plot, which necessarily
fails.
Plot(): Variable and axis value labels increased in size
for R Markdown and R by itself analyses.
ANOVA(), BarChart(),
Histogram(), Plot(),
Regression(), ttest(): A tibble that is not in
the user workspace, instead in a package, is now properly converted to a
standard R data frame upon which the internal function’s code depends,
which also permits more flexibility in the packaging of data in general
to these functions, such as with the pipe operator.
ANOVA(): Overall p-value now available for the
one-way ANOVA as the statistic in an output object, called
p_value, such as output object a$p_value in
a <- ANOVA( ... ).
getColors(): To address color blindness, the

viridis and Okabe-Ito were added as
qualitative palettes, such as for the bars of a bar chart.
sort_by(): New name for the Sort()
function, now deprecated, to maintain consistency of lower-case
functions being utility functions.
Plot(): For Trellis plots, indicated with
by1 and by2 parameters, assessment of
replications of unique values is done only if 1000 or fewer unique
values to save both space and compute time for information that is not
of such value anyhow.
Plot(): For a run chart, parameter
run=TRUE, the successive points in the plot are now by
default joined with line segments, which can be stopped by setting
parameter segments=FALSE.
Plot(): Parameters lab_cex and
axis_cex for size of value labels and axis labels, scaled
smaller for visualizations in R run alone, without RStudio.
Plot(): To address color blindness, when there is a
by grouping, default is now to not only vary the fill color
but also the shape of the plotted points.
Regression(): Parameter mod for
moderation analysis in a two-predictor model added.
ttest(): Parameter quiet added to turn
off text display at the console if set to TRUE.
order_by(): Old function name was
sort_by(). However, Base R now has a function with that
name, so to avoid confusion, the lessR function was renamed
to order_by().
ANOVA(): One-way ANOVA with parameter
graphics=FALSE now works.
BarChart(), Plot(): Qualitative color
palette hues was the default for the default color theme,
colors, but now also works explicitly when specified as the
value for the fill parameter.
BarChart(): Now works for color
parameter specified as a vector.
interact(): Interactive analyses resets label and
axis plot sizes to larger, now set back when saving the pdf and also
when re-plotting.

wrong lowercase expression piechart() instead of
PieChart().
Plot(): With a linear fit line, b0 and b1 now
reflect the specified number of digits according to parameter
digits_d.

variable scatterplot, when listing the continuous variable first, the
name of the categorical variable is now listed in the title of the text
output.
Plot(): For a run chart with parameter
run=TRUE, parameter scale_x now properly
allows for a custom set of ticks for the Index on the
x-axis.

Correlation(), ttest(): Vastly speeded up for
data sets much over 500 data values, substantial improvement on large
data sets.Plot(): Parameters jitter_x and

values of their assigned values, or, set to NULL to
activate the default value of the range of the variable divided by
50.

about hidden window removed.
pivot(): If na_remove is
FALSE, the missing data value for the aggregated statistic
