  4. Click on Download R for Windows
  5. Click on base
  6. Click on Download R 4.0.2 for Windows
  7. Install R as you would install any other Windows program

Obtaining and installing RStudio

You must install R prior to installing RStudio. RStudio is also simple to install:

  1. Go to
  2. Click on the link RStudio under the Products tab
  3. Click on the RStudio Desktop box
  4. Choose the DOWNLOAD RSTUDIO DESKTOP link in the Open Source Edition column

  1. Windows, macOS, and Linux users also can compile the source code directly, but for most it’s a better idea to install R from already compiled binary distributions. ^
  2. New versions of R are released regularly, so the version number in Step 6 might be different from what is listed below. ^
  3. As the name implies, all mirrors provide the exact same software. The mirror is usually fast; otherwise choose a mirror close to your geographic location. ^
