Right, sorry. I was a bit over-simplifying my problem, because I thought
this can be done with a general plot parameter (something like lty), and
most of the graphs I am plotting are actually straight regression lines.
The tougher cases are those wher I want to shade the area inside /
outside a specific contour line (produced with 'contour'). Can this be
done as well?
Thanks for your help,
