Thanks for those detailed explanation and the time taken to write them.

Yes sure, I went up to 10, but no success.

The easiest way is to send the data and the script off list. I will do it.

I did not try this one....
Actually, I found my way out easy with csr() in splancs, and did not
fight too much with spsample. My question on the list was just for
general information

I was wondering too... and chose r-help because I though the question
was of 'general' interest enough. This is debatable indeed...
Thank you anyway for your answer, and see you in a few minutes off list...
Cheers,
Patrick
