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.
tmap is available on CRAN (the latest version is 1.11, published on 2017-11-24). Installation is straightforward:
install.packages("tmap")However, for some operating systems require additional libraries. The installation procedure is as follows:
Windows No additional installation required.
Linux (Ubuntu) See installation script.
macOS See http://www.kyngchaos.com
