tmap_style {tmap}R Documentation

Set or get the default tmap style

Description

Set or get the default tmap style. Without arguments, the current style is returned. Also the available styles are displayed. When a style is set, the corresponding tmap options (see tmap_options()) will be set accordingly. The default style (i.e. when loading the package) is "white".

Usage

tmap_style(style)

Arguments

style

Name of the style. When omitted, tmap_style() returns the current style and also shows all available styles. When the style is specified,tmap_style() sets the style accordingly. Note that in that case, all tmap options (see tmap_options()) will be reset according to the style definition. See tm_layout() for predefined styles, and tmap_style_catalogue() for creating a catalogue.

Details

Note that tm_style() is used within a plot call (so it only affects that plot), whereas tmap_style() sets the style globally.

After loading a style, the options that defined this style (i.e. the difference with the default "white" style) can be obtained by tmap_options_diff().

The documentation of tmap_options() (details and the examples) shows how to create a new style.

Value

The style before changing
