• Added modern.sh script, demonstrating GMT modern mode.

gmt 2.0.2 (2020-11-23)

• Maintenance release.

gmt 2.0-1 (2017-09-12)

• Removed importing of unnecessary packages.

gmt 2.0-0 (2017-06-20)

• Adapted package to GMT version 5.

gmt 1.1-9 (2011-02-09)

gmt 1.1-1 (2007-08-02)

• Improved psxy(), pstext(), and psclose() so they no longer expect a Mercator-projected map, but any kind of map.

• Simplified gmt.system(), thanks to improved system() in R 2.5.0.

gmt 1.1-0 (2007-07-29)

• Added function num2deg() to convert numeric to degrees, the opposite of deg2num().

• Changed gmt() so quiet=TRUE by default, and files .gmtcommands4 and .gmtdefaults4 are created in dirname(file) instead of R working directory.

• Changed psxy(), pstext(), and psbar() so temporary GMT input files are saved directory dirname(tempdir()) instead of R working directory. These temporary files are later removed by psclose().

• Changed psclose() so the bounding box declaration is moved to the postscript file header, and GMT input files are removed from temporary directory. If cleanup=TRUE, the files .gmtcommands4 and .gmtdefaults4 are also removed.

• Improved r2gmt() to support # commented table header.

• Added scripts example.bat and example.sh that mimic the behaviour of the ‘gmt’ package.

• Improved help page examples.

gmt 1.0-3 (2005-10-18)

• Improved help pages.

gmt 1.0-2 (2005-10-02)

• Added function gmt.system() to handle the interface between R and system commands, passing invisible=TRUE on operating systems that support that argument.

gmt 1.0-1 (2005-10-01)

• Improved performance by changing approach from shell(“cmd>file”) to ps<-system(“cmd”);writeLines(ps,file). Demo runs four times faster.

• Added help pages for all functions.

• Submitted to CRAN.

gmt 0.9-1 (2005-09-27)

• Added argument ‘ref’ to psbar() to standardize bar height.

• Added function gmt() to initialize GMT session, making .gmthome(), gmtdefaults, and gmtset() obsolete. The package assumes that binaries are in the PATH and GMTHOME is defined.

• Added function r2gmt() to write GMT input files, making .data2gmt() and .file2gmt() obsolete.

gmt 0.9-0 (2005-09-25)

• Added functions .data2gmt(), .file2gmt(), .gmthome(), deg2num(), geodist(), gmt(), gmtdefaults(), gmtset(), psbar(), psclose(), pscoast(), pstext(), and psxy().

• Added example objects demo.bar, demo.coast, demo.set, demo.text, and demo.xy.
