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
