map.set.lat

integer. Initial latitude to center the map, a value in [-90, 90].

map.legend.variable

character. The name of the column to use for the legend. It also defines the legend title.

map.legend.labels

character. A vector with names for the legend's items. Must have the same length than 'map.legend.colors'.

map.legend.colors

map.area.fill.opacity

numerical. Opacity of the areas, a value between 0 and 1.

map.show.areas

character or logical. One of TRUE, FALSE, 'always', 'never'. If TRUE or FALSE, a checkbox is displayed under the map.

map.min.zoom

integer. Minimal zoom for the map, between 1 and 12.

table.hide.columns

chatacter. Name(s) of the column(s) to hide in the interactive table. Note that these columns can be searched using the 'Search' form anyways.

table.filter

character. Whether and where to use column filters: 'none': no filters, 'bottom' / 'top': put column filters at the bottom or top of the table.

table.pageLength

integer. Number of rows displayed on each page of the table.

data.download.button

logical. Dispay or not a button to download the dataset.

tabs.contents

This function launches the 'spatialCatalogueViewer' application.

The dataframe for data has mandatory and optional columns: Mandatory: resource.name: Name of the resource (HTML contents is possible). coordinates: Either 'lon' and 'lat' columns or 4 columns named 'bbox.lon1', 'bbox.lat1', 'bbox.lon2', 'bbox.lat2' (where lon1 and lat1 refers to the north-west corner of the area and lon2 and lat2 to the south-east corner).

Optional: * resource.popup: HTML contents for the map pop-up.
