r - How to merge 2 vectors alternating indexes?

Question

I would like to merge 2 vectors this way :

a = c(1,2,3)
b = c(11,12,13)
merged vector : c(1,11,2,12,3,13)

How could I do it ?

Answer 1

This will work using rbind :

c(rbind(a, b))

For example:

a = c(1,2,3)
b = c(11,12,13)

c(rbind(a,b))

#[1]  1 11  2 12  3 13
