Dear R-sig-mac list members,

When checking packages --as-cran with R 4.2.0 (and R 4.2.0 patched), 
I'm seeing multiple warnings (and a NOTE) concerning the HTML version 
of the package help-page manuals. The warning appears for every .Rd 
file in all of the packages that I've checked. I didn't see this 
problem before R 4.2.0.

I'm writing to the r-sig-mac list rather than r-package-devel because I 

Unfortunately the authors of this are not on r-sig-mac.

don't encounter the same problem under Windows. Nor does it appear on 
the CRAN check pages for the packages.

This check is only done if you have 'tidy' on the path.? My Monterey M1 
MBP has

auk2% tidy --version
HTML Tidy for Mac OS X released on 31 October 2006 - Apple Inc. build 2649

I think that is far too old.? The short answer is to ignore these, or 
update tidy (from http://binaries.html-tidy.org/) which (5.8.0) finds 
different issues for car that I do not see on Fedora (with 5.7.16).

Probably your Windows machine does not have tidy installed.

I know that there's been discussion of adding an HTML manual, which 
seems a good idea, but I didn't realize that this has apparently 
already been implemented.

Has anyone else experienced this problem or does anyone understand its 
source? AFAIK, there's nothing unusual about the R installation on my 
Mac, but of course there may be some setting that inadvertently turned 
on checking the HTML manual.

--as-cran turned it on ((f tidy is available).

Here's an example (with many lines elided, . . .):
