How to combine two lists in R

Question

I have two lists:

l1 = list(2, 3)

l2 = list(4)

I want a third list:

list(2, 3, 4).

How can I do it in a simple way? Although I can do it in for loop, I am expecting a one-liner answer, or maybe an in-built method.

Actually, I have a list:

list(list(2, 3), list(2, 4), list(3, 5), list(3, 7), list(5, 6), list(5, 7), list(6, 7)).

After computing on list(2, 3) and list(2, 4), I want list(2, 3, 4).

Answer 1

You can use the c() function to combine two lists as follows:

l1 = list(2, 3)

l2 = list(4)

> c(l1, l2)

[1] 2
