The “format” Function in R

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

• Purpose: To format numeric or date-time objects for pretty printing.

• General Class: Data Manipulation

• Required Argument(s):

• x: A numeric or date-time object to be formatted.

• Notable Optional Arguments:

• ...: Additional arguments depending on the class of x and the desired format.

• Example:

• # Example usage
  numeric_value <- 12345.6789
  
  # Format the numeric value with commas and a specified number of digits
  formatted_numeric <- format(numeric_value, big.mark = ",", digits = 2)
  
  print(formatted_numeric)

• In this example, format is a built-in function in base R, and it is used to format a numeric value (numeric_value) by adding commas as thousands separators and rounding to a specified number of significant digits. The x argument is required, and additional optional arguments (big.mark and digits) are used for formatting. The result is a formatted character string.
