[R] Using data stored in a file for a heatmap

[Richard Müller]

Hi all,
I just try to get familiar with levelplot() for generating heatmaps. I
have x, y, z-data stored in a file: e.g.:

"file.csv":
0 0 0.1
0 1 0.5
0 2 0.4
1 0 0.3
1 1 0.4
1 2 0.6
...

I can use scan() for generating the matrix for R:
inp <- scan("file.csv", list(0, 0, 0))
How can I feed inp into levelplot()?

Thanks a lot for your help

Richard
