[R-pkg-devel] Public URLs for help for versions of base packages

On Thu, 29 Jun 2023 20:22:47 +0100

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.

Best regards,
Ivan
