Hi all,
I have a little problem selecting some rows from a data.frame.
I'd like to select the rows where a determinated column take a
partivolar value.
For example:
tab
id x y
1 24-2005 1621814 4834991
2 24-2005 1621856 4834907
3 24-2005 1621763 4834956
4 25-2006 1622330 4835189
5 25-2006 1622533 4834834
6 25-2006 1622535 4834909
7 25-2006 1622543 4834803
8 28-2005 1622798 4835043
9 28-2005 1622299 4835129
I'd like to select the row where id=25-2006
I searched on the search of the R site but I did'nt find anything of simple.
Can someone help me?
Thank you very much
Leonardo
