Currently I have R version 3.4.1 with "purrr" package version 0.2.3. The problem that I'm having is the "purrr" package doesn't have "contains" function and whenever I try to use "contains" function, it just gives me the "contains" function from "dplyr" package. How do I get "contains" function in "purrr" package?
