Basics: Boxes & Toasters

R is a system of storage (Boxes) and transformation (Toasters).

Variables (The Box)

Use <- to save data into a name.

Code snippet

Save the number 55 into a variable called patient_age patient_age

Functions (The Toaster)

Functions take input, perform an action, and return output. Look at the snippet below

Code snippet

calculate_rectangle_area <- function(length, width) {
  area <- length * width
  return(area)
}

# Example usage:
calculate_rectangle_area(10, 5) # Returns 50
