The “sprintf” Function in R

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

• Purpose: To format and concatenate strings with the help of a format specification.

• General Class: String Manipulation

• Required Argument(s):

• fmt: A format specification string.

• …: Additional arguments to be formatted according to the format specification.

• Notable Optional Arguments:

• None

• Example:

• # Example usage
  name <- "John"
  age <- 30
  
  # Create a formatted string
  formatted_string <- sprintf("Hello, my name is %s and I am %d years old.", name, age)
  
  print(formatted_string)

• In this example, sprintf is a built-in function in base R, and it is used to create a formatted string by substituting placeholders in the format specification string ("Hello, my name is %s and I am %d years old.") with the values of the variables name and age. The fmt argument is required, and additional arguments (name and age) are used for substitution. The result is a formatted string.
