Make list of vectors by joining pair-corresponding elements of 2 vectors efficiently in R

Question

I have 2 vectors:

v1 <- letters[1:5]
v2 <- as.character(1:5)

> v1
[1] \"a\" \"b\" \"c\" \"d\" \"e\"
> v2
[1] \"1\" \"2\" \"3\" \"4\" \"5\"


        

Answer 1

mapply(c, v1, v2, SIMPLIFY = FALSE)
#$a
#[1] "a" "1"

#$b
#[1] "b" "2"

#$c
#[1] "c" "3"

#$d
#[1] "d" "4"

#$e
#[1] "e" "5"

(OR more precisely with respect to your OP which returns an unnamed list use mapply(c, v1, v2, SIMPLIFY = FALSE, USE.NAMES = FALSE) ).
