r-help,
I can't seem to get the below data organized in such a manner so as to
generate a contour plot
using any of the functions {lattice.contourplot, base.contour,
base.filled.contour}. I was wondering
if anyone could please tell me what I need to do to accomplish this.

I believe this was discussed about two days ago -- check the archives under the subject "density plot - beginner's question" -- and there were some good answers. Basically, the x and y vectors have to be increasing and response or Level, as you call it, needs to be in the form of a matrix of dimension length(x) by length(y). If the response/Level is not in the form of a matrix, you will need to smoooth or interpolate. -roger _______________________________ UCLA Department of Statistics rpeng at stat.ucla.edu http://www.stat.ucla.edu/~rpeng On Wed, 15 Jan 2003, mhoward wrote:> r-help, > > I can't seem to get the below data organized in such a manner so as to > generate a contour plot > using any of the functions {lattice.contourplot, base.contour, > base.filled.contour}.

Roger, Thanks, that information was exactly what I needed. I searched the site for info, but spaced the email archives....won't make that mistake again.
