Hi,
My package is failing on CRAN check on r-devel-windows-x86_64-new-UL.
https://cran.r-project.org/web/checks/check_results_string2path.html
It seems the problem is that there is no available font that meets the
condition in the following code. Is it irrational to assume at least
one TrueType or OpenType font is installed in the system?
available_fonts <- systemfonts::system_fonts()$path
# string2path supports only TrueType or OpenType formats
ttf_or_otf <- available_fonts[grepl("\\.(ttf|otf)$", available_fonts)]
This would be an empty character vector on my Alpine Linux server as
well. The system_fonts() there only contain ".pcf.gz" files from
"/usr/share/fonts/misc/".
Note that the "systemfonts" package on which you rely currently also
fails on that CRAN check flavour for a similar reason
(https://cran.r-project.org/web/checks/check_results_systemfonts.html).
On my Alpine Linux system, from example("register_font",
package="systemfonts"):
fonts <- system_fonts()
plain <- sample(which(!fonts$italic & fonts$weight <= 'normal'), 1)
bold <- sample(which(!fonts$italic & fonts$weight > 'normal'), 1)
italic <- sample(which(fonts$italic & fonts$weight <= 'normal'), 1)
## Error in sample.int(length(x), size, replace, prob) :
## invalid first argument
(as there are no italic fonts).
HTH,

I'm wondering if I need to release a new version to avoid this test
failure. Note that, the other Windows r-devel machine
(r-devel-windows-x86_64-new-TK) doesn't fail. So, it might be just
that something is wrong with r-devel-windows-x86_64-new-UL.
Any suggestions?
Best,
Hiroaki Yutani
