## Interacting with R

If you are familiar with the R programming language and the environment for statistical studies, then you can easily transfer the accumulated material for use in Mathematica. To do this, you need to enable the `RLink`

package and download the **paclet** for R using `RLinkResourcesInstall`

:

When launching the `RLinkResourcesInstall`

function, you will be asked to confirm the installation, and after this, the process of downloading the necessary files will start.

To start a connection with R, you need to call the `InstallR`

function. For example, let's set the value of the
`myR`

variable using the `RSet`

function and then read it using the `REvaluate`

function:

With the help of the `REvaluate`

function, you can also declare functions written in R and execute them in Mathematica. For example, let's declare a function that returns the cube of given numbers:

To avoid the repeated calling of the `REvaluate`

function every time the `thrd`

function is called, you can use `RFunction`

:

In this example, we will...
