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. Commented Dec 4, 2013 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"
