Can you describe how function closures can be used in R?
- Function closures allow functions to retain access to their enclosing environment even after the outer function has finished executing
- Function closures enable functions to take other functions as arguments
- Function closures provide a way to define functions on the fly within another function
- Function closures allow functions to return other functions
Function closures in R allow functions to retain access to their enclosing environment even after the outer function has finished executing. This enables nested functions to "remember" the values of variables from their parent function's environment. Closures are powerful for creating functions with persistent state or for creating functions on the fly within another function.
