"The stringr package is used for working with strings in R. It provides several useful functions to manipulate, clean, and analyze text data. Here are some examples:
- str_trim(): Removes leading and trailing whitespace from strings
- str_to_lower() / str_to_upper(): Converts strings to lowercase or uppercase
- str_replace_all(): Replaces all occurrences of a pattern in a string with another string
- str_extract(): Extracts a regular expression match from a string"
