I'm looking for a source of online help for R base packages, which covers all versions (for some reasonable value of "all"). So e.g. the equivalent of `?lm` for R 4.1.0.
These live in the R source tree, under src/library: https://svn.r-project.org/R/trunk/src/library/ For the actual releases of R, you may have to go looking at the branches inside that repository, e.g., the following command: svn log \ https://svn.r-project.org/R/branches/R-4-1-branch/src/library/stats/man/lm.Rd ...should tell you the history of ?lm until the latest R-4.1-patched. Do the Git mirrors track these release branches? The branching model of Subversion [*] is different from the Git model, so perhaps not.
The wch/r-source mirror tracks the releases. It takes svn tags and branches and converts them all to git branches. For example, here's the help for Rd2HTML from R 2.9.0: https://github.com/wch/r-source/blob/tags/R-2-9-0/src/library/tools/man/Rd2HTML.Rd Duncan Murdoch
