Hi
I use pixmapIndexed
tmp.vimp <- array(0,c(x.dim,y.dim)) tmp.vimp <- pixmapIndexed(tmp.vimp, col=rainbow)
to plot values of a 2D matrix. I 'fill' the pixmapIndexed like:
for (x in 1:x.dim) {
for (y in 1:y.dim) {
[EMAIL PROTECTED],y] <- my.matrix[x,y]
}}how can I define, that the colors are painted e.g. according the rainbow palette?
plot(tmp.vimp) paints all 'pixels' in red even though I specified it with col=rainbow (see above)
many thanks
cheers

p.s. is there an easier method for 'painting' the values of a 2d matrix?
