Steps to Install R and RStudio

Follow these procedures to  install R and RStudio in your system.

Step 1 – Install R

Download the R installer here – Download R

Download R

Run the installer. Default settings are fine. If you do not have admin rights on your laptop, then ask you local IT support. In that case, it is important that you also ask them to give you full permissions to the R directories. Without this, you will not be able to install additional packages later

Step 2 – Install RStudio

Download RStudio here.

Download Rstudio

  • Once the installation of R has completed successfully (and not before), run the RStudio installer.
  • If you do not have administrative rights on your laptop, step 2 may fail. Ask your IT Support or download a pre-built zip archive of RStudio which doesn’t need installing. The link for this is towards the bottom of the download page
    • Download the appropriate archive for your system (Windows/Linux only – the Mac version can be installed into your personal “Applications” folder without admin rights).
    • Double clicking on the zip archive should automatically unpack it on most Windows machines.
