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
