Hi, 
if I have a dataframe such that 

ID Time  Earn
1        1        10
1        2        50
1        3        68
2        1        40
2        2        78
2        4       88
3        1        50
3        2        60
3        3        98
4        1        33
4        2        48
4        4       58
.....
....
.....

Now if I have to select the all the rows from the data frame which does not 
include rows with certain IDs, say for example (prime) ID == 2 & 3, how do I do 
it 


Thanks

Rith
