Hi all,

I just wanted to report an error that I've been geting:
When I run duplicateCorrelation on this vsn object I get an error message.
If instead of using the vsn object I use the result of an "expres(
vsn.object)" function call it apparently works.
I could be mistaken, but I don't think that I upgraded my packages or R and
duplicateCorrelation after the last time I used duplicateCorrelation
succesfully.

Thanks a lot!
