No R interpreter defined: Many R related features like combination, code checking and help won't be available

For someone who looking solution for this, this is because when you install pycharm, you select to install R plugin but you don't have R interpreter in your machine. Solution is:

  1. Install R interpreter as explained by @sagarsys
  2. In Idea 2018 (Ubuntu), go to: File -> Setting. Looking for "plugin" in the vertical tab, and then uncheck "R language Support". Or if you don't need R, just uninstall it.

You need to install the R-Project files from Berkley.

Go to: https://cran.cnr.berkeley.edu

Download and install the package which corresponds to your OS. You are going to want the base distro.

Go back to your new project in PyCharm and open File->Settings

Select "Languages & Frameworks" then "R-Language"

You will add the location of the Rgui.exe file now installed on your PC. (On Windows, this is typically "C:\Program Files\R\R-3.4.3\bin\x64\Rgui.exe"). You will want to select either x32 or x64 depending on your OS.

The program will proceed to update "Skeletons" and you should be good to go.


If you are working in Python and you are getting such error, Then this may be due to adding of the plugin R Language Support during installation of JetBrains Pycharm.

So, to remove this error you need to go to settings->plugins->Installed

There you can select The R Language Support plugin and uninstall that plugin
