[STATSGRASS] about image() function in R and colors

[javier garcia]

Hi!

I've got a map in R imported from a GIS (GRASS) as a vector of factors.
So I've got 20 different levels in the map and I've created a vector of custom 
colors of exactly 20 colors in lenght.
I'm trying to use image()  (really plot.grassmeta() that call image()) to plot 
the map with those colors but it doesnt work and the colors are changed.

I would like that all points belonging to level1 are color 1 , and so on...

Please could you tell me if this procedure is not correct?


Best regards,

Javier
