gsDesign 3.6.2 (April, 2024)
Documentation
- Add new vignette on conditional power and conditional error, see
vignette("ConditionalPowerPlot")
(beb2957, 727fe20, 57394fe).
- Fix roxygen2 warning and use magrittr pipes in vignette for consistency (#131).
Testing
- Move independently programmed functions for validation as standard test helper files (#130).
gsDesign 3.6.1 (February, 2024)
New features
gsBoundSummary()
now has the as_rtf()
method implemented to generate RTF outputs for bound summary tables (@wangben718, #107).
plotgsPower()
gets new arguments offset
and titleAnalysisLegend
to enable more flexible and accurate power plots (plottype = 2
) (@jdblischak, #121, #123).
Improvements
- The plotting functions now use
dplyr::reframe()
to replace dplyr::summarize()
when performing grouped cumsum()
(@jdblischak, #114).
- The plotting functions are updated to use the
.data
pronoun from rlang with ggplot2::aes()
. This simplifies the code and follows the recommended practice when using ggplot2 in packages (@jdblischak, #124).
hGraph()
now uses named guide
argument in the scale_fill_manual()
call to be compatible with ggplot2 3.5.0 (@teunbrand, #115). Note: this function has been deprecated and moved to gMCPLite since gsDesign 3.4.0. It will be removed from gsDesign in a future version. Please use gMCPLite::hGraph()
instead.
Documentation
vignettes("SurvivalOverview")
is updated with more details and minor corrections (@keaven, #126).
- Fix equation syntax in plotting function documentation to render math symbols properly (@keaven, #118).
gsDesign 3.6.0 (November, 2023)
Breaking changes
gsSurv()
and nSurv()
have updated default values for T
and minfup
so that function calls with no arguments will run. Legacy code with T
or minfup
not explicitly specified could break (#105).
New features
gsSurvCalendar()
function added to enable group sequential design for time-to-event outcomes using calendar timing of interim analysis specification (#105).
as_rtf()
method for gsBinomialExact()
objects added, enable RTF table outputs for standard word processing software (#102).
Improvements
toBinomialExact()
and gsBinomialExact()
: fix error checking in bound computations, improve documentation and error messages (#105).
print.gsSurv()
: Improve the display of targeted events (very minor). The boundary crossing probability computations did not change. The need is made evident by the addition of the toInteger()
function (#105).
toInteger()
: Fix the documentation and execution based on the ratio
argument (#105).
- Update the vaccine efficacy, Poisson mixture model, and toInteger vignettes (#105).
- Standardize and improve roxygen2 documentation (#104).
gsDesign 3.5.0 (July, 2023)
sfPower()
now allows a wider parameter range (0, 15].
toInteger()
function added to convert gsDesign
or gsSurv
classes to integer sample size and event counts.
toBinomialExact()
function added to convert time-to-event bounds to exact binomial for low event rate studies.
- Added “A Gentle Introduction to Group Sequential Design” vignette for an introduction to asymptotics for group sequential design.
as_table()
and as_gt()
methods for gsBinomialExact
objects added, as described in the new “Binomial SPRT” vignette.
- In
plot.ssrCP()
, the hat
syntax in the mathematical expression is revised, resolving labeling issues.
ggplot2::qplot()
usage replaced due to its deprecation in ggplot2 3.4.0.
- Link update for the gsDesign manual in the documentation, now directly pointing to the gsDesign technical manual bookdown project.
- Introduced a new hex sticker logo.
gsDesign 3.4.0 (October, 2022)
- Removed restriction on
gsCP()
interim test statistic zi (#63).
- Removed gMCP dependency. Updated vignettes and linked to vignettes in gMCPLite (#69).
- Added deprecation warning to
hGraph()
and suggested using gMCPLite::hGraph()
instead (#70).
- Moved ggplot2 from
Depends
to Imports
(#56).

gsDesign 3.2.2 (January, 2022)
- Use
inherits()
instead of is()
to determine if an object is an instance of a class, when appropriate
- Correctly close graphics device in unit tests to avoid plot output file not found issues
- Minor fixes to hGraph() for multiplicity graphs
- Minor fix to nBinomial() when odds-ratio scale specified to resolve user issue
- Minor changes to vignettes

gsDesign
and gsSurv
gsDesign 3.0-5 (January, 2018)
- Registered C routines
- Fixed “gsbound”
- Replaced “array” by “rep” calls to avoid
R CMD check
warnings

nBinomial1Sample()
- Updated documentation and code (including one default value for an argument) for
nBinomial1Sample()
to improve error handling and clarity
- Updated
sfLDOF()
to generalize with rho parameter; still backwards compatible for Lan-DeMets O’Brien-Fleming
gsDesign 3.0-3
- Introduced spending time as a separate concept from information time to enable concepts such as calendar-based spending functions. The only user function changed is the
gsDesign()
function and the change is the addition of the parameters usTime
and lsTime
; default behavior is backwards compatible.
gsDesign 3.0-2 (February, 2016)
- Simplified conditional power section of gsDesignManual.pdf in doc directory
- Corrected basic calculation in
gsCP()
- Eliminated deprecated ggplot2 function
opts()
gsDesign 3.0-1 (January, 2016)
- More changes to comply with R standards (in NAMESPACE -
importFrom
statements - and DESCRIPTION - adding plyr to imports) ensuring appropriate references.
- Deleted link in documentation that no longer exists (gsBinomialExact.Rd).
- Last planned RForge-based release; moving to Github.
gsDesign 3.0-0 (December, 2015)
- Updated xtable extension to meet R standards for extensions.
- Fixed
xtable.gsSurv
and print.gsSurv
to work with 1-sided designs
- Update to calls to ggplot to replace show_guide (deprecated) with
show.legend
arguments where used in ggplot2::geom_text
calls; no user impact
- Minor typo fixed in
sfLogistic
help file
- Cleaned up “imports” and “depends” in an effort to be an R “good citizen”
- Registered S3 methods in NAMESPACE
gsDesign 2.9-4
- Minor edit to package description to comply with R standards
gsDesign 2.9-3 (November, 2014)
- Added
sfTrimmed
as likely preferred spending function approach to skipping early or all interim efficacy analyses; this also can adjust bound when final analysis is performed with less than maximum planned information. Updated help(sfTrimmed)
to demonstrate these capabilities.
- Added
sfGapped
, which is primarily intended to eliminate futility analyses later in a study; see help(sfGapped)
for an example
- Added
summary.spendfn()
to provide textual summary of spending functions; this simplified the print function for gsDesign objects
- Added
sfStep()
which can be used to set an interim spend when the exact amount of information is unknown; an example of how this can be misused is provided in the help file
- Fixed rounding so that
gsBoundSummary
, xtable.gsSurv
and summary.gsDesign
are consistent for gsSurv
objects
