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.

equal spacing of the polygons in levelplot key (lattice)

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

Thanks Dennis. This almost works. Is there a way to make the rectangles in the key the same size? In this example five rectangles of the same area evenly arrayed? Can the key be coerced into being categorical? The data I want to work with are not spatial but it occurs to me that this is a common mapping task (e.g., in this example you might want to label these colors 'low', 'kind of low', 'medium low', etc. or map land covers or such.) I'll look at the sp or raster plotting equivalent.
# 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) ))

OK, how about this instead?
# library('lattice')
levs <- as.vector(quantile(volcano,c(0,0.1,0.5,0.9,0.99,1)))
levq <- seq(min(levs), max(levs), length = 6)
levelplot(volcano, at = levs,
colorkey = list(at = levq,
labels = list(at = levq,
labels = levs) ))

Whoa. Tricky. That's great. Thanks!
