rle is extremely cool!!
This is really an impressive method to reduce vectors to point where you
need to do calculations. This really helped! Thanks a lot!

Ah, the request was 'hidden' in the subject of the message, apologies!

Well, can you algorithmically describe what you are trying to do? Your
example is not sufficient to determine it. For instance, are you trying to:
1) remove repeated elements of a vector and concatenate the first
element at the end?
2) remove repeated elements of a vector and concatenate the

4

4

Thanks in advance
