Reformat variables

In the video, you saw how to use clean_names() from the janitor package to convert all variable names to snake_case. Here is how:

library(janitor)
young_bakers3 <- young_bakers3 %>% 
   clean_names()

The function clean_names() takes an argument case that can be used to convert variable names to other cases, like "upper_camel" or "all_caps".

Let's practice using the messy_ratings tibble. Remember you can use ?clean_names to see the function arguments and how to use them.
