Hi all,

Tnx for all the replies:
Mike Colvin provided a simple answer in one step.

Bats.cast <- dcast(data = Bats.melt, formula = Species ~ Location, fill =0)

FYI the 0 for NA is correct in this application as the NAs do not 
represent "missing data" but actually no occurrence of a critter in a 
given habitat location so the values need to be a 0.

Tnx again,

Bruce
