Yes, the current design does not anticipate the possibility of
duplicated row and column names. A fix may or may not be simple; I
will look into it.

[Rd] Surprising behaviour of levelplot in lattice package
Hi Deepayan,
levelplot from the lattice package produces a peculiar output when
called on a matrix whose column or row names contained duplicated
elements. In particular, the plot contains white stripes, and the
arrangement of data regions and axes labels seems messed up. I did not
see this documented (my apologies if this is an oversight) and guess
that it is unintended:
library("lattice")
m = matrix(runif(12L), ncol=3L)
colnames(m) = c("A", "A", "B")
rownames(m) = c("x", "y", "y", "z")
print(levelplot(m))
Best wishes
Wolfgang
