element-wise concatenation of string vectors

Question

Say I have two character vectors:

a <- c("a", "b", "c")
b <- c("1", "2", "3")

How do I merge them such that I get:

ab <- c("a1", "b2", "c3")

A bit of googling would have gotten you `paste`. The linked question tells you enough about the function to be able to use it for your problem. — TheComeOnMan, Dec 04 '13 at 20:12

You can use paste or paste0:

> a <- c("a", "b", "c")
> b <- c("1", "2", "3")
> paste0(a, b)
[1] "a1" "b2" "c3"
