1.4 Renaming variable names for sanity sake

The best method is to use the clean_names() function from the janitor package.

depress <- depress_raw %>% janitor::clean_names()

A base R soluion is to use `tolower() to turn all variable names to lower case.

## names(depress) <- tolower(names(depress))
tolower("ThIs MIXTure of CAPS and lowercase WILL alL be conVERteD to LoWeR CAsE")
## [1] "this mixture of caps and lowercase will all be converted to lower case"
