What to do when an error occurs: "No R interpreter is defined: a function associated with R, as the end, check the code and help will not be available. You can set interpreter in Settings - > Languages - >R"

i tried so many ways i couldn't solve it 

You have to go to File -> Settings -> Project Intrepeter on your PyCharm.....then i believe you'll see nothing or wrong path setup, change it to your correct Python interpreter, i would tell you to install Python 3.6 from Python.org if you don't have it yet, then point this Project interpreter to it, hope this help you

No did not help, I even re-installed hoping to solve this problem. I even online can't find a similar problem

This error seems very strange, could you please specify what custom plugins do you have installed?

Дык забыл наверно програмку поставить?:

Could you solve the problem. I'm having the same error message and not able to type anything on py file. 

Please let me know. 

thanks

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 7, 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. 

This message annoyed me for a considerable time. I use MACOS (OSX) and eventually I solved this buy doing the following:

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 sush file on MAC this is /Applications/R.app/Contents/Resources/sush

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

Of course this could all be wrong and it simply removes the Message, Then again that's all I wanted for now.

我也遇到了相同的问题，昨天解决了，Fighting！

Why is nobody willing to help resolve this problem? I have had it for weeks and have tried uninstallng and reinstalling several times.  I have tried linking the right folder.  Although members of the community have tried to resolve this, its clearly not resolving the problem.  

Agreed. I'm having the same issue. I've reinstalled multiple times I'm about ready to just say fuck it and grab an IDE that works and will remain free after I'm no longer a student. The entire point of me being here is to become "addicted" to your product so I'll buy it when I'm done being  a student.... not this way. =/

its very simple un tick R Language Support....Cool

Hello guys I am also facing the same problems stupid r problem in this pycharm please help me 

just go to tools and turn off vim emulator

Go to Preferences -> Plugins and serach for "r language" you will find R language support, and uninstall it if you don't need R language.

I had the same problem and here is the fix i found. Do nothing, it's not a big deal if you check the error it's only for code checking and auto completion. i think when you first installed PYCHARM you also installed some language support plugins that is why you have this error. It's not a big deal and it won't affect your program at all so leave it be.

The more important questions is given that 'R' seems to be an essential requirement to important features of PyCharm, according to this error message, why is this not automatically included?  Or readily available as a plugin?

"08:57 No R interpreter defined: Many R related features like completion, code checking and help won't be available. You can set an interpreter under Preferences->Languages->R"  

It should also be noted it should read 'Settings->' not 'Preferences->

Hi Martin,

>The more important questions is given that 'R' seems to be an essential requirement to important features of PyCharm, according to this error message, why is this not automatically included?  Or readily available as a plugin?

It is available as a plugin and could be installed when installing PyCharm or in Settings/Preferences | Plugins.

>It should also be noted it should read 'Settings->' not 'Preferences->

Depending on the OS it is Settings or Preferences.

Hi Daniil

if you don't need to use R Language in the future maybe Xyfu1994's reply will be solved your problem

if not.... close PyCharm and install R application, then launch PyCharm

1.click File> settings > Languages & Frameworks > R Language 

2. added the path which you install R application 

done

Thanks Muhammad Marzouk it WORKS!

Install an R language (interpreter) 

https://cran.cnr.berkeley.edu/bin/windows/base/

Setup it in the IDE 

Puedes hacer desde un terminal:

sudo apt-get update
sudo apt-get install r-basel

luego suerte (debería de desaparecer el mensaje con los plugins activados...)


suerte...

@Eloyotero,

Sorry, can't read Spanish, but it seems like an issue related to apt repository or Linux OS, and not related to IDE.

Tambien puedes ir a plugins --> settings --> installed  y ahi desactivas R, vim , bash support , osea lo que al principio instalaste :) suerte.

Once R installed, need the configuration to be done in Setting-> Language -> R langauge with default path C:\Program Files\R\R-3.4.3\bin\x64\Rgui.exe..

Then in project interpreter, these needed packages should be added.

I was having all these above issues, so I had inlcuded all these and then donot see any issue. Hope this would be helpful..

I get continuous error of 'warning: unknown option -f' after I point the R Language interpreter to RGui.exe

if you not work with R lang or not use packages which depend or use R, you can just disable R language plugin

Some like Alt+Ctrl+S -> Plugins -> Pick tab "Installed" ->  Find plugin "R Language Support" or same depend from R interpreter -> unchech & restart IDE
