Isolating a column within a loop
...el, "_mean_",index$year[i], index$month[i], sep=''), ????????????? mean(get(paste(model, index$year[i], index$month[i], "[,3]", sep='')))) ???????? } Error in get(paste(model, index$year[i], index$month[i], "[,3]", sep = "")) : ? object 'cccma207101[,3]' not found The error message I'm getting is strange, because this object does exist: str(cccma207101[,3]) ?num [1:61538] 0.687 2.661 0 0 0 ... If I leave the "[,3]" out of the loop, the code seems to work fine - so I'm isolating this as the cause of the problem for now....
