How to embedR

Community Support

Hello, wondering if someone can help,

I am trying to embedR so I can call the changepoint package from q, but can’t seem to get R embedded properly.  I am looking through the github page

https://github.com/KxSystems/embedR

I’m just trying to test quickly with w32

| Windows | Open the archive and copy content of the embedr folder (embedr\*) to %QHOME% or c:\q
Copy R_HOME/x64/.dll or R_HOME/i386/.dll to QHOME/w64 or QHOME/w32 respectively. |

I’ve set on windows env var

R_HOME=C:\R\R_3.6.1



I've copied all dlls from R_HOME/bin/_i386_/.dll to QHOME/w32



but when I try to load rinit.q I'm getting error

I see now that version 1.0.0 is the only version to work on w64 is that correct?

Hi Roni,

Thanks for the message. I just had a look at following the instructions from the github and was able to install and run the 32 bit install on Windows with release 1.0.0 without any issues. I’ll need to check the 64 bit release on Monday but I believe an install is possible using the instructions provided at least with the 32 bit version. 

If you ensure that the embedr.dll which is in the w32 folder in that release is in your %QHOME%\w32 folder, the ‘specified module error’ you’re seeing is often seen when the required dll is not in the correct location. I’ll look at improving the instructions and the repository in general in the coming weeks. If you have any more questions please let me know here or email fusion@kx.com

All the best,

Conor
