Hi, Thanks to ggplot2 (and to Hadley Wickham) I managed to plot some nice graphs (not as fast as in a movie but it is ok). One thing I am still looking for is a way to add the values on the contour lines (like with the contour function).
I read the stat.contour help page but I haven't found my case. Is it possible to do it or not ? Thanks for your help.
