[R] "Simplifying" matrices ?

[Sérgio Nunes]

Hi again,

the previous answers were great. I was able to do what was planned.
Now, I would like to do the following to a matrix:

|| year | event | team | total ||

where I can have multiple "event" per "team", but each "team" only has
a "year" and a "total". Thus, this table has multiple lines for the
same "team" where only the "event" changes.
Considering this, how can I output this:

|| year | team | total ||

where each "team" occurs only once, and the "event" was discarded.

Hope I made myself clear.
Thanks in advance.

This is a great mailing list.
