Bruce,

I'm not sure what's going on since I tried this on my Linux system running
R 3.0.0 and just did:

library(reshape2)
help(cast)

and the help for 'cast' came up. There was no indication to me that
'reshape' was needed and I can not see a dependency in CRAN for 'reshape'.
But I built R from source when installing R 3.0.0 and all the packages I
use had to be reinstalled...

Great research, BTW!

Tom
