str_replace_all() vesus str_replace()

On this page there is an inadvertent error. The error wasn’t picked up because in this particular case, the code generates the same outcome.

The book code:

messy %>%
  mutate(income_before = 
         str_replace(income_before, "[$]", ""))

Should read:

messy %>%
  mutate(income_before = 
         str_replace_all(income_before, "[$]", ""))

The difference between str_replace_all() and str_replace() is that the former replaces all instances, where as the later only replaces the first instance. Generally, you would want to use str_replace_all().
