Many of your arguments don't make sense for dotplot (they do for barchart).

Hard to say without any version information. The following uses
grouping by default with R 2.2.1 and lattice 0.12-11 (both dotplot and
barchart):

pd = as.table(matrix(sample(c(rep(0, 10), 21:30), 20 * 6, TRUE), 20, 6))
dotplot(prop.table(pd, margin = 1), auto.key = list(space = "right"))
barchart(prop.table(pd, margin = 1), auto.key = list(space = "right"))

This is not a very useful form. What does str(pd) say?
