[R] R grahics: Save as hangs computer

[Richard M. Heiberger]

The good news, you don't have to shut down R.  Several control-G in
the *R* buffer in emacs will recover control.  A second attempt in the
same GUI graphics device did get the postscript file saved.

A workaround for this problem is to use the command line, rather than
the GUI menu, to save the file.  This line
    dev.copy2eps()
works.

I discovered that it is necessary to set
   options(chmhelp=FALSE)
when running R from emacs as the chmhelp is also freezing R
and the help system.  I am using  R-2.4.1 on Windows.

Use
   ?dev.copy2eps
for details on the command line dev.* commands.

Follow-up should go to the ess-bugs mailing list.
