The “tolower” Function in R

• Package: Base R (No specific package, it’s a built-in function)

• Purpose: To convert characters in a character vector to lowercase.

• General Class: String Manipulation

• Required Argument(s):

• x: A character vector to be converted to lowercase.

• Notable Optional Arguments:

• None

• Example:

• # Example usage
  words <- c("Apple", "Banana", "Orange", "Grape")
  
  # Convert all characters in the vector to lowercase
  lowercase_words <- tolower(words)
  
  print(lowercase_words)

• In this example, tolower is a built-in function in base R, and it is used to convert all characters in a character vector (words) to lowercase. The x argument is required, and there are no additional optional arguments. The result is a character vector with all elements converted to lowercase.
