| gmt {gmt} | R Documentation |
Initialize a GMT session by setting graphical parameters and current postscript file.
gmt(par=NULL, file="map.eps", style="s", quiet=TRUE)
par |
optional string of GMT parameters,
"PARAMETER1=value1 PARAMETER2=value2 ...", passed to
gmtset. |
file |
postscript filename used in subsequent calls to
GMT plot functions, passed to options() |
style |
default units and values: "s" for SI
(international) or "u" for United States, passed to
gmtdefaults. |
quiet |
whether current settings should be displayed. |
The file argument can be supplied with (recommended) or without
a full directory path. Without a path, the R working directory is used
(see getwd and setwd).
File type should be ‘.eps’ when PAPER_MEDIA is A4+
or letter+, but ‘.ps’ otherwise.
See the GMT documentation for details on graphical
parameters, gmtdefaults, gmtset and other
GMT commands.
List containing the current options("gmt.file").
If par is NULL, no GMT parameters are changed,
but the current parameter values and postscript filename can be
reviewed.
If par is a string (empty "" will do), a file named
‘.gmtdefaults4’ is created in the current map directory,
dirname(file). It can be removed later using psclose().
