[jim holtman]

Is this what you want:

> df
       f1      f2
1   Maj I Minor A
2   Maj I Minor A
3   Maj I Minor A
4  Maj II Minor A
5  Maj II Minor B
6  Maj II Minor B
7 Maj III Minor B
8 Maj III Minor C
9 Maj III Minor C
> df[!duplicated(df),]
       f1      f2
1   Maj I Minor A
4  Maj II Minor A
5  Maj II Minor B
7 Maj III Minor B
8 Maj III Minor C
