Portable R and Python Support
this Software looks really promising and helpful for my use case especially for larger projects.
Since I only work on portable R and Python versions, I have no PATH variables available.
Maybe it is possible to configure the executable path in the app settings and/or in each block individually in order to have the ability to use different versions of R and python in one project.
Did you try to set paths in settings? If you click on the "gear" icon in the interface, you should be able to edit the search path without directly editing the $PATH variable.
As for having different versions of R and Python in one project, can you be more specific, why would you need this?
