Thematic Maps

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.

tmap: thematic maps in R

Build Status AppVeyor Build Status License CRAN Downloads

tmap is an actively maintained open-source R-library for drawing thematic maps, written by Martijn Tennekes. The API is based on A Layered Grammar of Graphics by Hadley Wickham and resembles the syntax of ggplot2, a popular R-library for drawing charts.

Installation

tmap is available on CRAN. The latest version is 1.10 (2017-05-10).

The tmap packages relies on the R packages rgdal and rgeos, which depend on the external libraries gdal, proj.4 and geos. On Windows, these are embedded in rgdal and rgeos. On Linux (Ubuntu), these libraries can be installed as follows:

sudo apt-get install libgdal-dev
sudo apt-get install libproj-dev
sudo apt-get install libgeos-dev

See source pages for gdal, proj, and geos. For Mac OS users, see http://www.kyngchaos.com.

Also, tmap relies indirectly on the R package V8. For Linux (Ubuntu), the v8 library needs to be installed for this:

sudo apt-get install libv8-3.14-dev

Development

Odd numbered versions will be development versions and even numbered versions stable CRAN releases.

The latest development version can be installed using devtools. In order to use the development version of tmap, it is recommended to use the development version of tmaptools as well (see tmaptools)
