Dear R users,

I have a table with the following form

STATION  X       Y
1        -70    30
1        -70    30
1        -70    30
2        -72    29
2        -72    29
2        -72    29
2        -72    29

How want to extract unique value for those columns ... I am sure it is very simple, but I can not achieve to find the correct way !

I want to obtain something like

STATION    X     Y
1        -70    30
2        -72    29

Thanks !!!
