Is R isn't installed on your machine?

[Nelson Mok]

Yes, it is. R x64 3.1.3

[Tomas Petricek (Info)]

I’m not 100% sure, but I think that the R provider looks for 32bit version of R by default (on Windows).

Could you try installing 32bit R and see if that works?

 

If it does work with 32bit but does not work with 64bit, then I think we need to do some work to make it compatible with both.

Could you please open an issue for this on GitHub: https://github.com/BlueMountainCapital/FSharpRProvider

 

Thanks,

Tomas

Hi Tomas,

After uninstall R x64 3.1.3 and install R x32 3.1.3, visual studio cannot recognize namespace(RProvider.``base``, graphics and stats).

With  R x64 3.1.3 , namespace can be recognized, but cannot not be compile and got error message ( Windows Registry key 'SOFTWARE\R-core' not found in HKEY_LOCAL_MACHINE nor HKEY_CURRENT_USER)

Regards,

Nelson.

Hi Nelson,

Hmm, that is odd – you need to check some option during R installation to write version to the registry, but AFAIK, it is checked by default – so unless you uncheck it, that should work.

 

Can you please produce a log file using the instructions from here: http://bluemountaincapital.github.io/FSharpRProvider/diagnostics.html

And then report the issue here:

Hi Tomas,

   The issue has been reported. Thanks.

Regards,

Nelson.

It works, install both 32 and 64 R binaries in the windows 8.1. Thanks
