I would like to do a leveplot, with the kind of file here enclosed. I assume I should create a matrix in R, then use the function 'image'. As I am not

Dear all; I have a data set with 3 groups and 2 response variables, say z1 and z2, and I would like to create a single plot (using the levelplot function) showing on the first row the leveplots for z1 for each group and on the second row levelplots for z2 for the same groups. I tried plot.trellis using the split option and it's OK but what I would like to achieve is something similar to what you can get in the case that you'd have 6 groups and only one response, i.e., 3 plots on t...

I've likely missed something in the documentation, but have been at it a couple days without finding a solution (other than
