Trying to execute the following code produces a 'not a valid postscript' error from various postscript readers (gv, ggv, ghostscript). A very similar code works fine.

<CODE>

postscript()

plot( 1:100, ylim=c(1,700), type='n', log='y')

abline(v=seq(0,100,10))
abline(h=10)
abline(h=seq(0,100, 10)) # Comment out this line and it works fine

dev.off()

</CODE>

Opening the resulting file 'Rplots.ps' gives the following error from ghostscript (version 7.05)...

GNU Ghostscript 7.05: Unrecoverable error, exit code 1

Looking at this just now I see the problem, but if a ps file is written, it should be viewable, so I think this is still a bug.

Cheers,
Dan.
