I am looking for an elegant way of producing an indexed frequency table.
In particular, I have observations on three variables:

ID var1 var2 var3
1     1    2    1
2     2    3    1
3     5    4    5
4     6    6    6
...
And I would like to produce a table showing only different patterns and
there observed frequencies, ie.

               var1 var2 var3 frequency
First pattern    1    1    1        54
Second pattern   1    1    2        43
