<rekado>Kabouik: about using older versions of R: you can get a long way with package transformations, rebuilding all R packages with that older version of R (provided by guix-past), but you'll find that many R packages (especially on Bioconductor) have hard requirements on R versions.

<rekado>so you would likely have to use guix time-machine to get to some older version of Guix and supplement that with R versions from Guix Past or from a manifest.

<rekado>using advanced package transformations pretty much requires the use of Guile

<rekado>the problem itself is complicated enough that there cannot be a simple turnkey solution. Most of the work is finding the right combination of old packages that work together.

<rekado>if the organization has the capacity for it, a research engineer position could be used for helping users to arrive at a manifest that would work for them.

<rekado>in my experience you cannot push this work onto users who refuse to learn even the least bit of Guile
