This is a recent addition to R checks. I am pretty sure that \doi{} with the suggested syntax does produce proper links in the documentation.

Hi,

When running R CMD check on R-devel, a CRAN note appears about \href{https://doi.org/...}{label} in Rd files. Like:

Found the following URLs which should use \doi (with the DOI name only):
   File ‘read_GRTSmh.Rd’:
     https://doi.org/10.5281/zenodo.2611233
     https://doi.org/10.5281/zenodo.3354403
   File ‘read_GRTSmh_base4frac.Rd’:
     https://doi.org/10.5281/zenodo.3354401

(Full output is at
https://github.com/inbo/n2khab/runs/2219662325?check_suite_focus=true#step:10:35)

The note does not appear in R 4.0.4.

The cause is documentation hyperlinks to doi.org, ** inside \href{} **:

./man/read_GRTSmh.Rd:42:\href{https://doi.org/10.5281/zenodo.2611233}{Zenodo},
is a monolayered GeoTIFF
./man/read_GRTSmh.Rd:73:\href{https://doi.org/10.5281/zenodo.3354403}{Zenodo},
and can only be
./man/read_GRTSmh_base4frac.Rd:33:\href{https://doi.org/10.5281/zenodo.3354401}{Zenodo}.
./man/read_GRTSmh_diffres.Rd:45:at
\href{https://doi.org/10.5281/zenodo.3354405}{Zenodo}), composed of ./man/read_habitatmap_stdized.Rd:68:\href{https://doi.org/10.5281/zenodo.3355192}{Zenodo},
that
./man/read_habitatmap_terr.Rd:117:\href{https://doi.org/10.5281/zenodo.3468948}{Zenodo},
that contains:
./man/read_habitatquarries.Rd:70:\href{https://doi.org/10.5281/zenodo.4072967}{Zenodo},
that contains:
./man/read_habitatsprings.Rd:83:\href{https://doi.org/10.5281/zenodo.3550994}{Zenodo}.
./man/read_soilmap.Rd:225:\href{https://doi.org/10.5281/zenodo.3732903}{Zenodo}.
./man/read_watercourse_100mseg.Rd:73:\href{https://doi.org/10.5281/zenodo.4452577}{Zenodo},
and contains two
./man/read_watercourse_100mseg.Rd:83:\href{https://doi.org/10.5281/zenodo.4420904}{\code{watercourses}}
data
./man/read_watersurfaces_hab.Rd:66:\href{https://doi.org/10.5281/zenodo.3386857}{watersurface
map of Flanders}.
./man/read_watersurfaces_hab.Rd:71:\href{https://doi.org/10.5281/zenodo.3374645}{Zenodo},
that contains:


Can this be resolved using \doi{} as suggested, while still resulting in a working link to doi.org? I didn't find a way to do that.

Perhaps a 'https://doi.org' address which does not show as such in the documentation (because of the clickable label) should still be allowed.


With regards
