# Install R Power BI

In this tutorial, youâ€™ll learn about **R in Power BI**. You’ll understand what is R and RStudio, and how to download them.

First, letâ€™s learn the basics. What is R?

Ris a programming language and free software environment for statistical computing and graphics. It is widely used among statisticians and data miners for developing statistical software and data analysis.

From the definition, R is essentially a programming language invented by statisticians for statisticians. It is thus perfect for statistical analysis in Power BI. Moreover, it also has great data visualization capabilities.

You can also use R for other techniques that work with large or unusual data sets. In this case, unusual data sets refer to images, book reviews, or writing websites. And because statistics is involved, machine learning can also be used to build predictive models. So youâ€™ll also be diving into machine learning basics like correlation and regression, but not necessarily machine learning in itself.

There are other used cases with Power BI and R. But again, the focus is on statistics and visualizations.

R is open source. That means that anybody is free to work with the code base of R. You have full rights to see, modify, and distribute it. With R, you have full intellectual control to do what you want.

## Downloading R For Power BI

There are two sources where you can download R: the **Comprehensive R Archive Network (CRAN)** or from the **Microsoft R Application Network (MRAN)**. This tutorial will show how to download R from CRAN.

Once the CRAN website loads, you’ll see there is an option to choose your OS or version of R. In this example, itâ€™ll be for **Windows**.

Once you select a version, you’ll be redirected to a new page. Select **install R for the first time**.

Youâ€™ll then be redirected to the download page. Select **Download R for Windows**.

Once the file has been downloaded, open it, and then install the software.

Just select the default options and continue pressing the **Next** button until you **Finish **the set up.

To check if R has been successfully downloaded in your computer, you can do a simple search and should find a folder labeled **R**.

Open the **version 4.1.1 **R program that matches your computerâ€™s specifications (x64 or x32). In this case, letâ€™s open **R x64 4.1.1**. This is now what the R program looks like:

Before you begin exploring, you first need to download **RStudio**. RStudio uses the R programming language to build statistical programs which is a necessity when performing statistical analysis. It is crucial to download R first before RStudio.

## Downloading RStudio

To download the RStudio Desktop version, go to **rstudio.com** and select **RStudio**.

Scroll down and then click on **RStudio Desktop**.

You can choose between the Free and Pro version.

In this case, the Free version is already sufficient.

Youâ€™ll then be redirected to the final download page. Click on **Download RStudio for Windows** if you are a Windows user. If not, there are other installers to choose from depending on your computerâ€™s OS.

Once the download finishes, launch the installer and continue to click **Next** until you reach the **Finish**. Similar to R, you donâ€™t have to change anything. The default settings will do.

Once you open the RStudio software in your computer, itâ€™ll look like this:

## Conclusion

R coupled with RStudio is a powerful statistical tool you can use in Power BI. In succeeding tutorials, youâ€™ll learn the different parts of the interfaces in R and RStudio. The next steps also include how to set them up to work with Power BI.
