That's an error: it has a missing argument and a missing parenthesis.

Note:

1) onefile is no longer set as an argument to pdf().

2) When you set onefile=FALSE, you will only get the last plot in your
file unless you give a file name of the type described on the help page.

3) *You* plotted the `nasty rectangles', so why are you aruprised you got 
them in the file?  If you don't want them, don't plot them!

Please follow more carefully the help you have already been given.
