the same sort of results one gets with base::aggregate.
Actually I see after looking at examples on the plyr-reshape-

With reshape I can cast with multiple functions:
library(reshape)
cast(x, month+variable~., c(mean,sd))
month variable

library(reshape)
cast(x, month+variable~., c(mean,sd))
month variable mean sd
