Hi I'm using lattice's function levelplot but when I choose the flag contour =TRUE I get very strange results. It looks like the contour lines have nothing to do with the "image" plot under ... Is there some known problem with this function ?

What version of lattice do you have ? Could you give an example ? e.g.,
data(volcano) levelplot(volcano, contour = TRUE)
looks OK to me.

Hi I'm using lattice 0.5-6 and R 1.6.0 in a SuSE 8.0 linux box. The volcano dataset is a matrix with x and y has margins and z has the values. I'm using a data.frame with 4 columns (x, y, z, year) and I'm using a z~x*y|year formula. The image result is ok but the contour is not ... Looking at documentation I understand that I the way I'm doing it is correct. I've uploaded two files, the dump of my dataset and a pdf with the result I'm getting with: levelplot(Zest~x*y, data=recs2001, contour=TRUE) in my web page (http://ej.freezope.org/R) If you can please take a look. Regards EJ

Hi, the problem is due to the fact that your data frame doesn't have z-values for all possible x-y combinations (equivalent to a matrix in contour with lots of NA's), which contourplot can't handle. This is definitely a bug in contourplot, and I will try to look into it. Deepayan
