How it works…

To write a function in R, there is a keyword in R called function. Using this keyword, you can write any type of customized function in R. In this recipe, the task is as follows:

1. Write a function that will take a numeric vector as input.
2. Then, it will calculate the mean and standard deviation internally.
3. Finally, it will give an output of the ratio of the standard deviation and mean.

Each of the input parameters is called the argument of a function. In this recipe, the input argument is vectorInput. You can use any numeric input vector to specify the input of this function by passing the argument as vectorInput=V1.

Within the curly braces, the actual calculation happened. In this case, the mean and standard deviation has been ...
