| ps.end {sfsmisc} | R Documentation |
Closes the PostScript file (postscript), openend by a
previous ps.do (or ps.latex) call, using
dev.off, and additionally opens a previewer for that
file, unless the previewer is already up. This almost provides
an ‘interactive’ device (like x11) for
postscript.
ps.end(call.gv= NULL, command = getOption("eps_view"),
debug = getOption("verbose"))
call.gv |
logical, indicating if ghostview (or the command given
by command) should be called. By default, find out if
ghostview is already runing on this file and only call it if needed. |
command |
character, giving a system command for PostScript previewing.
By default, getOption("eps_view") is set togv -watch -geometry -0+0 -magstep -2 -media BBox -noantialias
which assumes gv (aka ghostview) to be in your OS path. |
debug |
logical; if TRUE print information during execution. |
Depends heavily on Unix tools, such as ps.
