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!
