Error: package or namespace load failed for ‘caret’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called ‘recipes’

I tried to install recipes with this code- install.packages("recipes") after gotten the above error message, then tried to load caret with the code library ("caret"), still got the same error message above. I need help please.

Since you are using an old R version, the ipred package requires compilation to be updated, and for that, you need to have RTools installed in your system.

You can download a suitable version of RTools from here

Although, I would recommend updating to the latest R version (4.1.2) so you can get access to precompiled binaries

Thank you so much. It is working perfectly now, I updated to the newest R version as suggested.
