Yes, if you have the info files installed. Which I presume is the default; I
am on Linux where the distribution packages tend to have them. (I look after
the ess package for Debian/Ubuntu [but that is irrelevant as there are no
more ess releases, hint, hint, ...]).
I have quite a few:
edd@rob:~$ ls -1 /usr/share/info/*info*gz | wc -l
120
edd@rob:~$

C-h i gets you the list of all manuals the within-emacs info reader
knows / are in the standard info location (iirc you can override
with env vars, on Linux you generally do no need to)
m R Ex<TAB> then tab-completes to 'R Extensions' and
m R Intro<TAB> tab-completes to the 'R Introduction'
and so on. There are info-reading keyboard command shortcuts to browse. It is
actually the main way in which I read / have read / am reading these
files. (Though the quarto-built ones at https://rstudio.github.io/r-manuals/
are very nice to link to.)

Sure, why not?
