It was really the same answer as Phil.  Notice if you use a data.frame 
instead of a matrix, you don't have to recast to a 'matrix'-like form, 
and therefore the split call is a little simpler. Depending on what 
you're doing, it might or might not make sense.

initialDF <- 

split(initialDF, initialDF[,1])
