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

With the dplyr-package loaded use

bob=bob%>%mutate_at("phenotype", as.character)

if you only want to change the phenotype-column specifically.
