I was not aware of the R-FAQ, it seems to have some very useful tips, thanks for pointing there.
Regarding the 7.21 in the FAQ, I read it a few times but it did not lead me anywhere. For the moment I am blaming my inexperience with some R basics, I will come back after I do some more serious studying.

What searching did you do and why did it not find this FAQ or previous discussion of it? How could the documentation/search/etc. be improved so that you (and the next n people with this question) will find the answer easier? The most important of part of the FAQ answer is the last section where it points out that using a list will be much simpler. You mentioned in the first post that you were doing this in a loop, just start with an empty list, use paste (or sprintf) to create the name, and then assign it as a new element of the list with that name (e.g. mylist[[ sprintf('tmax.%d%d', var1, var2) ]] <- outputfromcomputations ). -- Gregory (Greg) L.
