R- list of combination of 3 item sets from n items

Question

I am getting a tough time in selecting the combinations of factors.

I have a vector as ("Ryan", "Leo", "Jack","Harry","Edd").

I want to get the list of of all combinations taken 3 of the names once.

I want to do it in R. Probably a resultant matrix will help me.

Answer 1

We can use combn

t(combn(vec1, 3))
