#> In addition to using pre-defined functions in R, you can also create your own custom functions based on your specific needs. For example, the `sum()` function adds up all the values of a given vector, while the `mean()` function calculates the average. #> R has a large number of built-in functions that perform a wide variety of tasks. #> To use a function in R, you simply call it by its name and supply any necessary arguments:

are the inputs to the function (also called parameters), and `output` is the value that the function returns. #> Here, `function_name` is the name you choose for your function, `argument1`, `argument2`, etc. #> function_name # Function code goes here The basic syntax of a function definition in R is as follows:

#> In R, function definitions can be created using the `function()` keyword.

Functions can be used to automate repetitive tasks, combine multiple operations into a single step, and create more complex programs.
