contourLines() starts a plot device
I want to use contourLines() to get contour line coordinate vectors, but I don't want to make a plot. However contourLines() insists on opening a graphics device. Is there a way tell it not to do this? > version platform i686-pc-linux-gnu arch i686 os linux-gnu system i686, linux-gnu status Patched major 2 minor 1.0 year 2005 month 04 day 20 language R Cheers, Pierre
