ps.end

R Documentation

Close PostScript or Acrobat Graphics Device opened by 'ps.do' / 'pdf.do'

Description

Closes the PostScript or PDF file (postscript,pdf), openend by a previous ps.do (or pdf.latex, or ...) 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 or pdf.

Usage

ps.end(call.gv= NULL, command = getOption("eps_view"),
       debug = getOption("verbose"))
pdf.end(call.viewer= NULL, command = getOption("pdfviewer"),
       debug = getOption("verbose"))

Arguments

`call.gv`, `call.viewer`	logical, indicating if the postscript or acrobat reader (e.g., ghostview or `acroread` or the command given by `command`) should be called. By default, find out if the viewer 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 to `gv -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.

Details

Depends on Unix tools, such as ps.

Examples

if(interactive() 
  ) {
    myPS <- tempfile("ex", fileext = ".ps")
    ps.do(myPS)
    data(sunspots)
    plot(sunspots)
    ps.end()

    tempfile("ex-sun", fileext = ".pdf") -> myPDF
    pdf.latex(myPDF)
    plot(sunspots)
    pdf.end(call. = FALSE) # basically the same as dev.off()
  }
  ps.latex(tempfile("ex2", fileext = ".eps"))
  plot(sunspots)
  ps.end(call.gv = FALSE) # basically the same as dev.off()
