tmap-package: Thematic Map Visualization

Description

Thematic maps are geographical maps in which spatial data distributions are visualized. This package offers a flexible, layer-based, and easy to use approach to create thematic maps, such as choropleths and bubble maps. It is based on the grammar of graphics, and resembles the syntax of ggplot2.

Arguments

Quick plotting method

qtmPlot a thematic map

Shape specification:

tm_shapeSpecify a shape object
------------------------------------------------------------------------------------------------------------------------------

Aesthetics base layers:

tm_polygonsCreate a polygon layer (with borders)
tm_symbolsCreate a layer of symbols
tm_linesCreate a layer of lines
tm_rasterCreate a raster layer
tm_textCreate a layer of text labels
tm_basemapCreate a layer of basemap tiles
tm_tilesCreate a layer of overlay tiles

Aesthetics derived layers:

tm_fillCreate a polygon layer (without borders)
tm_bordersCreate polygon borders
tm_bubblesCreate a layer of bubbles
tm_squaresCreate a layer of squares
tm_dotsCreate a layer of dots

Layout element:

tm_layoutAdjust the layout (main function)
tm_legendAdjust the legend
tm_viewConfigure the interactive view mode
tm_styleApply a predefined style
tm_formatApply a predefined format
