Dear list, I encountered a problem using function image() and argument breaks on a SpatialGridDataFrame object (package sp version 0.9-76, R version 2.12.1 (2010-12-16) on Ubuntu 10.04).
I had to use function as.image.SpatialGridDataFrame before to obtain the correct colored graphic: # Doesn't work: image(SDAzD.As.A2a.2080,breaks=c(seq(0,0.5,0.1),1),col=c(grey(seq(0.9,0.5,-0.1)),"dark green")) # Works: xyz <- as.image.SpatialGridDataFrame(SDAzD.As.A2a.2080) image(xyz,breaks=c(seq(0,0.5,0.1),1),col=c(grey(seq(0.9,0.5,-0.1)),"dark green")) Is this a normal behavior ?
