Description

ps.options needs to be called before calling postscript, and the default values it sets can be overridden by supplying arguments to postscript.

Usage

ps.options(..., reset = FALSE, override.check = FALSE)

Arguments

...

arguments paper, horizontal, width, height, family, encoding, pointsize, bg, fg, onefile, print.it, colormodel and append (ignored) can be supplied.

reset, override.check

logical arguments passed to check.options. See the Examples.

Value

A named list of arguments.

Examples

ps.options(bg = "pink")
utils::str(ps.options(reset = TRUE))

### ---- error checking of arguments: ----
ps.options(width=0:12, onefile=0, bg=pi)
# override the check for 'onefile', but not the others:
utils::str(ps.options(width=0:12, onefile=1, bg=pi,
                      override.check = c(FALSE,TRUE,FALSE)))
