Yes, it *is* available from CRAN:  You can see it when looking into the

4.4.0/           , specifically the
4.4.0/Recommended/ sub directory.

Recommended packages should be built as part of R
unless *you* really want to *not* get them by choosing at
configure time, not to get them via extra flag
  --without-recommended-packages.

So, well, you got what you wanted.

Yes, because it has to provide Matrix to R versions before 4.4.0
and Matrix 1.7-0 has  'Depends: R (>= 4.4.0)'

(why would you explicitly choose *not* to have the
 recommended packages when they *are* recommended .. :-b )

That's not true (see above), but it maybe true that
install.packages() does not work directly -- I guess you
should get it to work with correct function arguments;
if not, you'd definitely have found a missing feature...
.. *and* Rstudio button clicking works even less, because it does
not allow to specify the install.packages() call.

.. and yes, ideally install.packages() would be smart enough to
figure that Matrix is recommended *and* that it should therefore
try the same location ( ./4.4.0/Recommended/ in this case) as
R's own  tools/rsync-recommended  script does.

Finally, I'd think it definitely would be nice for
install.packages("Matrix") to automatically get the correct
Matrix version from CRAN ... so we (R-core) would be grateful
for a patch to install.packages() to achieve this  (unless that
patch is too large or too much involved for reliable
maintenance).
