Could not find function mutate_if

Question

I am trying to use the function mutate_if under dplyr() package to convert all the character columns to factor columns. I am aware of alternate approaches for this transfromation, but I am curious to see how mutate_if works. I tried the following command:

df <-df %>% mutate_if(is.character,as.factor)

But I am geting a message, :

could not find function mutate_if

I reinstalled dplyr() but still I am getting the same error message.

Solution

When I was having this problem, I also got the error message "there is no package called 'pillar'" while loading the dplyr package. (Re-installing dplyr didn't seem to install pillar.) Installing the pillar package allowed things to work again.

There is a mutate_if listed in the index of the version of dplyr that is up-to-date per CRAN.

I checked the most recent pdf of CRAN there was noting.

Your powers of searching seem week, my friend. Pages 49 and 66 are listed in the Index and the string mutate_if appears 6 times in the version 0.5.0 document: cran.r-project.org/web/packages/dplyr/dplyr.pdf
