[R] "ghost" image in .eps file

[Prof Brian Ripley]

I can't see this in your examples: which viewer did you use?  I do see it 
in phantom.ps.

However, looking at resources.bygt.eps, the file is corrupt with a load 
of bytes after 

%%EOF

starting with nulls and then some postscript.  So I don't think this is an
R problem but an OS problem.  (Please see the posting guide about required
background info!) An intelligent viewer will stop at the %%EOF comment.

Please try deleting the file resources.bygt.eps, starting a new R session
and repeating the plot call.
