Dear R-packge-devel members,
I am writing to discuss the update from a while ago to the Matrix package,
which specifies a minimum requirement of R (>= 4.4.0).
As Matrix is a Recommended package and a foundational dependency for a vast
number of packages on CRAN (including lme4, mgcv, and hundreds or thousands
others), this version requirement has significant downstream implications
if applied everywhere. I am aware only of a few packages which updated
their minimum required R version matching Matrix as their dependency.
Because so many packages depend on Matrix, this change effectively raises
the "floor" for a large portion of CRAN to R 4.4.0. Is it true? Do we see
that a few thousands packages are not yet properly updated to R (>= 4.4.0)?
Or Most of the packages do not need the newest Matrix and the
install.packages matching somehow the newest Matrix fitted for a User R
Version.
I do not find anything direct in that matter in the R docs.
Thank you for your support.
Best regards,
