JASP and R installation on Windows

Hello.

I am about to install JASP on a Windoze machine, using the exe installer I just downloaded from the JASP site. I peeked inside the exe and see that it appears it will want to install a version of R. But I already have a version of R installed on this machine and I do not want to break it or interfere with it in any way.

Can some knowledgeable person please explain how the JASP exe installer handles this situation?

Thank you.

  • Hi Ether,

    You are not supposed to peek inside the exe! :-)
    To clarify: JASP uses R (and specific R packages) under the hood, so we need to bundle it together with the GUI routines. The JASP installation happens in a way so that it does not interfere with your usual R installation. Just treat it like a black box and you will be OK. If you need more details you can contact the programmers through the JASP GitHub pages.

    Cheers,
    E.J.

    Yes, I read a few bits here and there indicating that was the case, but without more details I'm a bit leary. I'm wondering exactly how that is accomplished under Windows.

    If you need more details you can contact the programmers through the JASP GitHub pages.

    I've never done that before. Would you post a link to help me get kick-started with that?

    The details I am concerned with are:

    • no changes to the existing R installation or associated libraries or low-level blas routines used by the existing R installation
    • no changes to the registry that would change the behavior of the existing R installation (like file associations etc)
    • no changes to the existing R environment variables that would change the behavior of the existing R installation
    • probably other Windows settings that I haven't thought of or am unaware of

    Thanks

  • Hi Ether,

    Really, this is not a problem. We do not make any of these changes. However, if you want to discuss this with our programming team, you can create an issue on GitHub (see the link on https://jasp-stats.org/feature-requests/). You have to create a GitHub login and then you are all set to go.

    Cheers,
    E.J.
