How to concatenate c(1,2,3) and c(4,5,6) to c(1,4,2,5,3,6) in R?

Question

How can I concatenate two vectors to get a vector with values alternatively from the first and second one?

Input

a<- c(1,2,3)
b<- c(4,5,6)

Output

c(1,4,2,5,3,6)

That's not going to interleave. – Elin Feb 15 '15 at 23:58 — Elin, Feb 15 '15 at 23:58
@Elin did you try it? – Peter Diakumis Feb 16 '15 at 00:00 — Peter Diakumis, Feb 16 '15 at 00:00

This is one way

> as.numeric(t(matrix(c(a,b), ncol = 2)))
[1] 1 4 2 5 3 6
