I am automatically creating several matrices to store results from different

If you want to calculate the number of days having greater than a certain
threshold of rain within a range of months, a function like this might
serve your needs.
raindays - function(data, monStart=1, monEnd=3, threshold=0.85) {
with(data, {
selRows - Month = monStart Month = monEnd Rain
I think it would be easier to keep track of what you're doing, if you save
the assignment to the very end of your for() loop. For example ...
# create an empty matrix to be used as a template
Mtemplate - matrix(data=NA, nrow=13, ncol=3,
