Examples

## first an eps-file test.eps is created, then a jpeg-file,
  ## finally the figure is plotted on the screen
  dir(pattern="test*")
  dev.list <- list(TRUE, 1)
  if (interactive()) dev.list <- c(dev.list, "jpeg")
  for (dev in dev.list) {
    Print(dev)
    size <- if (dev=="jpeg") 450 else 5
    err <- class(try(Dev(TRUE, dev, ps="test", height=size, width=size)))
    if (err!="try-error") {
      plot(0, 0, main=paste("dev=", dev))
      # readline("press return")
      Dev(FALSE)
    }
