Thanks very much for your answer. I�m trying the function �strtoi� but it fails to convert character to numeric after the command "set[index] <- strtoi(set[index])".
> strtoi(set[index]) ## This works: all values are numeric !!! [1] 1 2 3 4 2 8 9 7 > set[index] <- strtoi(set[index]) > print(set[10,1]) ## Problem: must be numeric !!!! [1] "1" Thanks very much for your help.
