In particular, please see the "Found the following HTML validation
problems" NOTEs in the "HTML version of manual" check for at least some
of the r-devel checks results.
R 4.2.0 switched to use HTML5 for documentation pages. Now validation
using HTML Tidy finds problems in the HTML generated from your Rd
files.
To fix, in most cases it suffices to re-generate the Rd files using the
current CRAN version of roxygen2. To check whether this already fixes
things, or whether additional changes you made fixed the problems (e.g.,
if the problem is from yourself directly generating HTML output), you
can grab HTML Tidy version 5.8.0 binaries from
https://binaries.html-tidy.org/ and, with FOO.Rd an Rd file for which
problems were found, run
R CMD Rdconv -t html /path/to/FOO.Rd -o FOO.html
tidy -qe --drop-empty-elements no FOO.html
(Alternatively, you can use R CMD check --as-cran using a current
version of R-devel.)
Note that
was removed from HTML5: you can use style attributes
(e.g., style="text-align: center;") instead.
Can you please fix as necessary?
Please correct before 2022-09-14 to safely retain your package on CRAN.
