Hi all,
I have a set of patterns which can occur in a series of (3) matrices. I
want to identify those and create a fourth one with the identifiers of
the cases.
Something like:
for (i in 1:l) {
for (j in 1:w) {
A[A[i,j]==1 D[i,j]==1

You are putting your results back into A which might change things
as you execute. This might be a faster way:
result - matrix(NA,dim(A)[1], dim(A)[2])
# now compute the cases
result[(A ==1) (D == 1) (P ==1)] - Case1
result[(A == -1) (D == -1) (P == -1)] - Case2
