[R] help for input

[yiping.fan@syngenta.com]

Hello, all,
    I have a question regarding data input.  For example: I have a file like
this
       Group exp value
 001 1  1   5
002   1  2  4
003   1  3  4
004  2   1  4
005 2    1  4
006  3    2  3
007  3   4 5
008  3  4  5
009   3  5  6
I read it using 
f<-read.table("infile")
we have 3 groups here,
group1 have 3 exps
group 2 havs 2 exps
group 3 has 4 exps
After I read the file,  how can I get the data for each group?   Thanks!

Yiping
