can someone tell me if there is an easier way to do this in R - create a
design matrix? thanks.
> design <- model.matrix(~
-1+factor(c(1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,2,3,3,3,3,3,3,3,3,3,4,4,4,4,4,4,4,4,4,5,5,5,5,5,5,5,5,5,5,5,5,5)))
# Creates an appropriate design matrix
can someone tell me if there is an easier way to do this matrix?
thanks.
