[R] Getting all possible combinations

[Christofer Bogaso]

Hi again,

I am exploring if R can help me to get all possible combinations of
members in a group.

Let say I have a group with 5 members : A, B, C, D, E

Now I want to generate all possible unique combinations with all
possible lengths from that group e.g.

1st combination : A
2nd combination : B
.....
5th combination : E
6th combination : A, B
7th combination : B, C
....
last combination: A, B, C, D, E

Ideally, I have a fairly large group so am looking for some
programmatic way to generate all possible combinations.

Any help will be highly appreciated.

Thanks for your time.
