Elemental concatenation of vector vectors

Question

Say I have two character vectors:

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

How to combine them to get:

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

Answer 1

You can use paste or paste0 :

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