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 & P[i,j]==1] <- Case1;
A[A[i,j]==-1 & D[i,j]==-1 & P[i,j]==-1] <- Case2;
etc....
}
}
the code seems to run, but is very slow.... Could anyone please suggest
a better approach? I was thinking that 3 matrices could be stacked in a
cube, and the column of a cube searched for a pattern, but am not sure
how to do that...
Thanks
Martin
