Add Text/Symbols to GMT Map

Description

Call GMT to add text/symbols to the active map and save in postscript format.

Usage

pstext(x, cmd="-JM -R -O -K", file=options("gmt.file"))

Arguments

x data frame, matrix, or filename containing the data to be plotted.
cmd string of arguments passed to pstext.
file filename where the map is saved.

Details

The data are arranged in seven columns: Lon, Lat, Size, Angle, Font, Justify, and Text, in that order. See help(r2gmt) for valid data file format when argument x is a filename. See the GMT documentation for details on pstext and other GMT commands.

Value

Null, but the map is annotated and saved in postscript format.
As a side product, a temporary file ‘lastTEXT.gmt’ is saved in the working directory.

Note

Assumes that GMT version 4 is installed, i.e. that pstext and other commands are in the path, and environment variable GMTHOME is defined.
