Try WBS.labs <- as.vector(WBS) WBS.labs[1] substr(WBS.labs[1],1,1) etc.. Cheers, Simon.
Hello 1/ 'priors' is a table looking like: "W123" "T678" "S789" 23 42 11 12 35 9 etc 2/ WBS <- labels(priors) gives me a result of class list and length 1 looking like: "W123" "T678" "S789" I want to read W123 into X[1] as W, T687 into X[2] as T and S789 into X[3] as S using substr(X[1],1,1) but I'm having trouble extracting each group of 4 digits from WBS Any help would be gratefully accepted. thanks Meredith
