Matrix is just a vector with the dim attribute. Assuming it is not referenced
by anyone, you can set any values to the dim attribute. As for the vector, you
can use SET_LENGTH() to shorten it - but I'm not sure how official it is - it
was originally designed to work, but there were abuses of TRU
Hi,
Is there a way to resize a matrix defined as follows:
SEXP a = PROTECT(allocMatrix(INTSXP, 10, 2));
int *pa = INTEGER(a)
To row = 5 and col = 1 or do I have to allocate a second matrix "b" with
pointer *pb and do a "for" loop to transfer the value of a to b?
Thank you
Best regards
Morgan
