You don't show code or a reproducible example, so I guess you want a general answer. Use the draw.colorkey() function inside the levelplot() call. It takes an argument key =, which accepts a list of arguments, including space, col, at, labels, tick.number, width and height (see p. 155 of the Lattice book). More specifically, the labels argument also accepts a list of values, with components at, labels, cex, col, font, fontface and fontfamily. You could attach the units as labels with a combination of at = and labels = inside the (outer) labels argument, something like
myAt <- c(1, 3, 5, 7, 9) myLab <- paste(myAt, 'cm') levelplot( ... draw.colorkey(key = list(labels = list(at = myAt, labels = myLab)), ... ) If that doesn't work, then please provide a reproducible example.
