This package provides functions to draw basic maps with GMT, along with helping functions that can be used to add more advanced features to a map.
It supports GMT version 4.0 and higher, and has been tested in Windows and Linux.
GMT users typically write shell scripts to draw maps. The gmt package is about interactive data analysis, rapidly visualizing subsets and summaries of geographic data, while performing statistical analysis in the R console.
