Dear R experts,
I am new to using the sp package and I am wondering how does one change
color palette in spplot()? The problem is that when I do:
library(sp)
data(meuse)
coordinates(meuse) = c(x,y)
spplot(meuse, zinc)
the middle class (zinc concentrations (803.4, 1149]) is plotted in white
Aleksey,
It seems you missed the documentation of ?spplot, or misunderstood. It
describes a col.regions argument, which accepts a color ramp.
spplot is a relatively thin wrapper around the functions xyplot (for
points or lines) or levelplot (for areas) in package lattice. If you
want to do all

no, you need to pass colors, not a color palette generating function.
Have you tried?
spplot(meuse, zinc, cuts=7, col.regions=cm.colors())
