Dear all,
I am trying to learn R.
Is it possible to find the mean of some rows (of some table) and to put it
in new table.
For example we have following table
date x y z
1 05-23-2001 7 1 3
2 05-24-2001 8 4 5
3 05-24-2001 6 0 0
4 05-24-2001 26 2 6
5 06-19-2001 0 7 0
6 06-19-2001 5 0 2
and I want to make the table
date x y z
1 05-23-2001
2 05-24-2001 (mean values for each day's)
6 06-19-2001
Is it possible to do this using R???
If possible pl. help me. Thanking you.
Regards,
mini
