I have data.frame in R which have a form like following:
ID Label1 Label2(code) total_number(it's a number)
1 AAA 2211123 100000
1 AAA 2222313 120304
2 AAB 2234123 234145
2 AAB 3123412 1000
4 ADD 1231566 200
4 AAB 3155032 30000
.
.
.
What I want to do is to make each Label2 as a feature however, when I make them as a feature I'd like to sort all Label2 who shares same Label1 together lexicographically.
Label1 has 162 different elments and Label2 has 1200around different elements.
So the final result would be look like :
ID 2211123(AAA) 222313(AAA) 2234123(AAB) 3155032(AAB) 3155032(AAB)
1 10000 120304 0 0
2 0 0 1000
3
4 300000
How can I do this?
