R help - Aug 2008 - contour lines in windows device but neither in pdf nor in postscript

Hi Patrizio,

No problem with either format on my system, though I am using 2.7.1 patched.
It's not mentioned as a bug fix for the patched version so surely was
working in 2.7.1. Probably something local.

HTH, Mark.

What viewers are you using?

Works for me (using ghostscript 4.61 and acroread 8.1.2) -- I even tried 
2.7.1 (as well as R-patched).
