[R] png plots

[Allin Cottrell]

I saw in the archive a post from Mark Wilkinson (Feb 1, 2003), saying
that some of his R-generated png plots came out overlapping.

I am seeing the same thing (with R 1.6.2 on Linux i686).  My input
file generated 4 plot files.  The first two were fine, but the last 2
featured a weird overlay of the remaining graphs.  The problem is not
seen with postscript of pdf output.
