I’d look into trying with groundhog: https://cran.r-project.org/web/packages/groundhog/index.html
Cheers F Federico Calboli Erityisasiantuntija, tutkimusrahoitus Palveluryhmät Luonnonvarakeskus Hi - I'm a postdoc at the University of Edinburgh who's urgently trying to install an older version of a package (Seurat) listed on CRAN but without success. The package is Seurat_4.4.0.tar.gz. I currently work on a M1 Macbook Pro (with Sonoma installed) with RStudio version 4.3.2 and tried to install the package using the following code: remotes::install_version(package = 'Seurat', version = package_version('4.4.0')) However this appears to be unsuccessful - I was wondering if there is any guidance on how to install these on M1 macbooks? I have also tried uninstalling and reinstalling R many times which again did not succeed. Any help you could give me on this would be much appreciated.
