Imagine you need to create a global variable within a function in R. How would you do this?

  • Define the variable using the <<- operator inside the function
  • Define the variable using the -> operator inside the function
  • Define the variable using the = operator inside the function
  • It is not possible to create a global variable within a function
To create a global variable within a function in R, you can use the <<- operator. By assigning a value to a variable using <<- inside a function, the variable becomes a global variable that can be accessed from anywhere in the program. However, it is generally recommended to limit the use of global variables within functions for better code organization and modularity.
