R help - Nov 2011 - equal spacing of the polygons in levelplot key (lattice)

Given the example:
R> (levs <- quantile(volcano,c(0,0.1,0.5,0.9,0.99,1)))
   0%  10%  50%  90%  99% 100% 
   94  100  124  170  189  195 
R> levelplot(volcano,at=levs)

How can I make the key categorical with the size of the divisions equally spaced
in the key? E.g., five equal size rectangles with labels at levs
c(100,124,170,189,195)?

Apologies if this is obvious.

Hi:

Does this work?

# library('lattice')
levs <- as.vector(quantile(volcano,c(0,0.1,0.5,0.9,0.99,1)))
levelplot(volcano, at = levs,
            colorkey = list(labels = list(at = levs,
                                                   labels = levs) ))

HTH,
Dennis
