Currently I have a data set looking like:
License Species Year HD Quota L.R.QTA L.R.QTA Success
Surplus
Permit Elk 1999 101 50 87 90
151 10
Permit Deer 1999 101 50 20 10
151 8
Permit Elk 1999 101 50 87 90
20 9
Permit Elk 1999 101 50 60 20
151 10
A9 Elk 1999 101 40 87
30 241 10
A9 Elk 1999 101 20 50
50 154 8
A9 Deer 2000 101 50 87 70
161 10
A9 Deer 2000 101 30 80 70
181 16
DeerB Elk 1999 201 50 87 70
161 19
DeerB Elk 1999 201 60 87 90
151 18
This dataset goes from 1999-2010 and I'm trying to sum all variables for by
hunting district and year. Therefore instead of having individual stats by
each HD I want to sum the stats that correspond to say year 1999 and HD 101.
Does anyone know an easy/quick way to do this? I'm a new user of R and Any
help would be much appreciated.
Steve
