Unfortunately your test generates a false positive for httr2 (
https://cran.r-project.org/web/checks/check_results_httr2.html) and other
tidyverse packages where we use the base pipe in examples, but carefully
disable them for older versions of R.
For exemple, in one of reported files 'iterate_with_offset.Rd' (
https://github.com/r-lib/httr2/blob/main/man/iterate_with_offset.Rd ),
we can see :
\examples{
req <- request(example_url()) |>
req_url_path("/iris") |>
req_throttle(10) |>
req_url_query(limit = 50)
...
the pipe '|>' is well used but I didn't find any check for R version
prior to 4.1. May be it is done elsewhere?
Best,
Serguei.

My guess would be that the new syntax is particularly prominently used
in examples: if so, it would be good to also have coverage for this.
In today's CRAN snapshot, there turned out to be 198 packages that use
4.1 syntax in examples but not in code, 5 packages that use 4.2 syntax
in examples but 4.1 in the code, and 3 packages that use 4.2 syntax in
examples but not the code. This may be slightly imprecise because I
don't have some of the Rd macro packages installed and run
Rd2ex(stages=NULL) on manually-parsed Rd files without installing the
packages.
Attaching a patch that checks the syntax used in Rd examples at the
same time as the main R code, not necessarily the best way to perform
this check. Is it perhaps worth separating R/* checks from man/*.Rd
checks? Should R CMD check try to reuse the Rd database from the
installed copy of the package?
