Hi, I would like to map 'a' to 'd' according to columns in 'data'. I would be grateful for your help.
library(tibble) a <- c(1,2,3,4,1,2) b <- c(1,2,3,4) c <- c("a","b","c","d") data <- tibble(b,c)
Are you looking for something like this? It will return a named vector.
> deframe(x = data)[a] 1 2 3 4 1 2 "a" "b" "c" "d" "a" "b"
