strip_non_alpha(df)

Arguments

df	The dataframe, tibble, etc, with the variables you want to tidy.

Value

A dataframe, tibble, etc, with new and consistent cases for variable names.

names(df)
#[1] "name_with_brackets[]"                "$$name_with_dollar_sign"            
#[3] "name_&&with&&_ambersand::_and_colon" "name_'with\"_quote"
