Hi all,
I have a binary matrix with NAs included. Each row and column
includes at least one NA, so I don't want to omit them. Is there a
way to sum across rows and columns, ignoring the NAs but not deleting
the row or column? If not, I suppose I can write a loop function, but
I have learned that it is best to stay away from loops if possible.
Thanks for any help,
Wade

Hi Wade,
The rowSums() and colSums() functions have a "na.rm" argument that you
could set to TRUE.
Would this solve your problem?
Cheers,
