The “str_remove” Function in R

• Package: stringr

• Purpose: To remove matched patterns 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 to remove the word "pie" from each element
  result <- str_remove(text, "pie")
  
  # Print the result
  print(result)

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