I think you need to be more specific. Which "downloaded package"? Which viewer? As the list info says: "We can't help if we don't know what the problem is."
FWIW, this format is used by many packages that I have installed on my machine and is rendered as a link on the CRAN package website, see https://CRAN.R-project.org/package=colorspace, for example. I can confirm that this format is not recognized in all HTML versions of package descriptions out there, maybe most prominently at https://rdrr.io/cran/colorspace/ and https://www.r-pkg.org/pkg/colorspace . The former does not even convert full URLs in the description text (such as the R-Forge URL). However, the lack of clickable DOIs seems to be a limitation of these websites not of your package description or the CRAN policy. The required <doi:10..../....> format is officially documented at https://www.doi.org/doi_handbook/2_Numbering.html#2.6.1 Finally, again citing the list info: "Please note that while R-package-devel contributors will do their best to provide you accurate and authoritative information, the final arbiters of CRAN submission is the CRAN team." ;) Best regards, Sebastian Meyer Am 24.02.21 um 09:25 schrieb Knut Krueger: > Am 22.02.21 um 14:58 schrieb Uwe Ligges: > >> Write it inline as in: >> >> See Author 1 (2021) <doi:10....> and Author 2 (2004) <doi:10......>. > > I see at the downloaded package that the urls are not usable by clicking. > means the doi <doi:xyz/1234567> has not been converted to > https://doi.org/xyz/1234567 > Any chance to fix this in the description file? > > > Regards Knut > > ______________________________________________ > R-package-devel@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-package-devel ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
