Usage

Arguments

par

style

default units and values: "s" for SI (international) or "u" for United States, passed to gmtdefaults

file

postscript filename used in subsequent calls to GMT plot functions, passed to options()

quiet

whether current settings should be displayed

Value

• List containing the current options("gmt.file"). If par is passed by user (even an empty string "" will do), a file named .gmtdefaults4 is created in the working directory. If quiet=FALSE, the current graphical parameter settings are displayed.
