PLEASE do use the R-help mailing list for questions about R.

which you are not at all talking.

Dear all,

I arrive to do density plots using the function "kde2d" , and from this do 
a countour plot. My problem is that I do not really understand what the 
labels for the different levels mean??? What I would like to obtain is a 
surface encompassing the 95 percentile of my values. In other words I would 
like the levels to represent, for example, the 90th, 95th and 99th 
percentiles of my values. I hope I have been clear.
Do you think you can help me??? I would be VERY grateful.


Thanks in advance
