[R] show and produce PDF file with pdf() and dev.off( ) in function

[Greg Snow]

As others have said, you pretty much need to do the plot 2 times, but
if it takes more that one command to create the plot you can use the
dev.copy function to copy what you have just plotted into another
graphics device rather than reissuing all the commands again.
