Convert data.frame columns from factors to characters

Question

I have a data frame. Let\'s call him bob:

> head(bob)
                 phenotype                         exclusion
GSM399350 3- 4- 8- 25- 44+         


        

Answer 1

Maybe a newer option?

library("tidyverse")

bob <- bob %>% group_by_if(is.factor, as.character)
