Hello Members,

I need to group a data.frame in a a specific way, like shown below,

DF raw is like this,

id col1 col2 score
1  A      B       40
2  B      C       55
3  C      D       4000
4  D      E        100
5  E       F        300

I want the out put as

List
[1]
A B C
[2]
D E
[3]
F
Basically the split should be based on the DF$score > 200, and all the col1
and col2 values should be aggrigated.

Request your kind help,

Regards,
karthick
