[R] A ggplot question

[Megh]

Thanks Ista for your mail. Here I wanted to have control on color-pallet. It
is because, here my entire plot window is subdivided in 3 sub-plots
horizontally, on basis if a factor-variable which contains three factors, 
using facet_grid(). Each sub-plot contains scatter-plot. I want to color the
points of each scatter-plot based on the corresponding factor (contained in
factor-variable). Therefore as you might agree in this case, there is no
need for additional color-pallet as the factor-description is handled by
facet_grid() function itself.

Any better idea how I can hide color-pallet?

Thanks,
