I did not look closely at the solutions that you were offered, but note that you did not specify in your post whether the numbers in your string were to be character or numeric variables after they are broken out into their own columns. I believe that they are character in the solutions, but you should check this. If you want them as numeric, e.g., for further processing, you will need to convert them. Or vice-versa.
