Incorrect: it plots on the default device for batch use, most likely 
pdf(), so look for a file Rplots.pdf.

You have ignored the posting guide so we do not know your OS.  On a 
Unix-alike, you could explicitly open X11() (quartz() on a Mac), but 
it would be closed again at the end of your script unless you arrange 
to pause the script.

Real names and the courtesy of a signature block are preferred here.
