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. X,Y,Level -31.105,86.911,3843 -3.385,86.911,3896 24.335,86.911,3874 -24.175,79.700,3900 -3.385,79.700,3927

...ner'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 cont...
