[R] String split and concatenation

[Greg Snow]

Steven,

I noticed that I hit the send button too early.  I answered the question you asked, but probably not the one that you should be asking.  Why do you want to do this?  It looks suspiciously like you are trying to create code to then evaluate.  That is usually like printing a document, scanning it back in, an importing it as a graphic in another document so they can change the size (yes this happens), instead of just changing the font size and margins.

If you tell us more of your ultimate goal, we can probably be more helpful.
