@ -187,7 +187,7 @@ That's because regular expressions are case sensitive.
There are three ways we could fix this:
- Add the upper case vowels to the character class: `str_count(name, "[aeiouAEIOU]")`.
- Tell the regular expression to ignore case: `str_count(regex(name, ignore_case = TRUE), "[aeiou]")`. We'll talk about more in @sec-flags.
- Tell the regular expression to ignore case: `str_count(name, regex("[aeiou]", ignore_case = TRUE))`. We'll talk about more in @sec-flags.
- Use `str_to_lower()` to convert the names to lower case: `str_count(str_to_lower(name), "[aeiou]")`.
This variety of approaches is pretty typical when working with strings --- there are often multiple ways to reach your goal, either by making your pattern more complicated or by doing some preprocessing on your string.
