R: how to change lattice (levelplot) color theme?

Question

The default theme on my installation is something which maps the values to pink and cyan. How to change it for example to a gray scale theme?

Answer 1

Thanks for the answers guys! It also helped me to find more information on the subject. I learned that I can control the scales of gray using for example the following:

levelplot(my_var, col.regions = gray(0:100/100))

which gives me 100 shades of gray from black (0) to white (1).

I'm using the function to plot gray scale images (photos) which I've pre-processed to a double matrix. I don't know if it's the best possible approach, but so far it works and I believe it gives me more options for graphing than the basic displaying options in the EBImage and rimage libraries. I don't know how I'd alter the palette to match displaying color images, but I'm glad I didn't have to do that so far...
