Hello, I'm am in the process of trying to port a RATS functions to R and have the problem, that RATS allows for the creation of submatrixes that are linked to their basematrix.
Basically it should work like this: a = matrix(1:(4*3),4,3) a # [,1] [,2] [,3] # [1,] 1 5 9 # [2,] 2 6 10 # [3,] 3 7 11 # [4,] 4 8 12 # This of course doesnt work :) b = submatrix(a,fromx=1,tox=2,fromy=1,toy=2) b # [,1] [,2] # [1,] 0 10 # [2,] 7 11 b[1,1] = 42 a[1,1] # [1] 42 so changes in the sub-matrix propagate to the "base" matrix. Does such a feature exist?
