[R] A problem with text manipulation

[Bert Gunter]

Christofer:

This reminds me of those IQ puzzles I took so many years ago as a kid:
Given the numbers 7, 22, 43, 5, 26,...    what are the next 3 numbers
in this series? I don't recall having a clue, and when I got older and
more mathematical, generally came to the conclusion that it could
logically be anything I wanted it to.

Anyway... that's my reaction to your post: I haven't a clue what rule
you used to construct the desired output from the input. But then
others may.  So of course I would not be able to tell you **how** to
write an R procedure that does it. But then others may. If not, I
would suggest that you reveal your secret.

Cheers,
Bert
