Hi
I have records like like this
X1 X2 State
34 72 state1
9 63 state1
49 31 state1
60 34 state1
80 73 state1
60 20 state2
59 87 state2
88 20 state2
71 66 state2
65 56 state2
59 16 state1
60 100 state2
I want to get the summarize value like mean median histogram for X1 and X2
based on state. I'm using FOR loop for this. Is there any method to remove
for loop and use apply or any alternatives
-----
Thanks in Advance
Arun
