Line for the server...
Maarten`s solution is brilliant! For such probs, let me recommend

for future reference, although in this particular case, the answer was at
least not obvious...

Subject: st: deleting duplicate observations by date
I have a data set with the following format:
id date price
1 1 400
2 1 500
2 2 450
2 3 450
3 2 600
3 3 .
Where I have multiple id's observed at different dates, and not necessarily
the same date. What I would like, is to delete all but the most recent date
and fill in the price with the most recent price observed.
For example:
id date price
1 1 400
2 3 450
3 3 600
Any clues on how to do this? I've played around with dup and duplicated but
still haven't found anything.
