Sorry, guess I wasn't clear enough. The code is for example only--it
works fine in R, but when sent across the R-(D)COM interface it does
not work. I have tried with many of the lattice graphics and a few
versions of R, but none work across the R-(D)COM interface. Again,
the code will work fine in a "pure R" environment, but fails when
passed over the COM interface.
Thanks
