[R-pkg-devel] Matrix and Mac OS

[Mikael Jagan]

Thanks.  We did see those ERRORs, stemming from use (since Matrix 1.6-0)
of amsmath commands in Rd files.  These have been supported since R 4.2.2,
but r-oldrel-macos-* (unlike r-oldrel-windows-*) continues to run R 4.2.0.
My expectation was that those machines would begin running R >= 4.2.2 well
before the R 4.4.0 release, but apparently that was wrong.

I am hesitant to complicate our Rd files with conditions on R versions
only to support PDF output for R < 4.2.2, but maybe we can consider it
for the Matrix 1.6-2 release if it is really a barrier for others ...

I had to fix a few things due to changes in the latest Matrix package because of how qr works and I thought, given the apparent API change, I should then require the latest version. My error is, "Package required and available but unsuitable version: 'Matrix'"

What version do MacOS version test Matrix with by default? Where is this documented? I assumes it always tested with the latest version on CRAN, so I'm a bit surprised. Or will this be resolved soon and I shouldn't bother CRAN maintainers with a new version of my package?
