Description

postscript start the graphics device driver for producing PostScript graphics. The file file is opened and the PostScript commands needed to plot any graphics requested are stored in that file. This file can then be printed on a suitable device to obtain hard copy.

The auxiliary function ps.options can be used to set and view (if called without arguments) default values for the arguments to postscript.

The postscript produced by R is EPS (Encapsulated PostScript) compatible, and can be included into other documents, e.g. into LaTeX, using \epsfig{file=<filename>}.
