The “str_remove_all” Function in R

• Package: stringr

• Purpose: To remove all occurrences of a matched pattern from a character vector using regular expressions.

• General Class: String Manipulation

• Required Argument(s):

• string: A character vector where patterns will be removed.

• pattern: A regular expression pattern to match.

• Notable Optional Arguments:

• None

• Example:

• # Example usage
  library(stringr)
  
  # Create a character vector
  text <- c("apple pie", "banana split", "cherry tart")
  
  # Use str_remove_all to remove all occurrences of the word "pie" from each element
  result <- str_remove_all(text, "pie")
  
  # Print the result
  print(result)

• In this example, the str_remove_all function from the stringr package is used to remove all occurrences of the specified pattern (“pie”) from each element of the character vector text. The resulting vector is then printed to the console.
