No, I'm sure they are aware of it.

OK - thanks. I will consider it. Do you think it's useful to mention this bug/feature request to the r-devel mailinglist? Maybe it's possible to update pandoc on the test systems.

I think it makes no difference. You can't have avoidable warnings or errors in a CRAN submission. This is a problem with the test platform, not with your package (assuming you have declared dependencies properly).

If I add this two lines a the beginning of my vignettes the Solaris CRAN check will produce an error when building the vignettes. But as far as I understood it, it's better to have warnings than errors when releasing to CRAN. Therefore it would be better to avoid this solution, or?

You can check for a sufficient pandoc version using this code: if (requireNamespace("rmarkdown") && !rmarkdown::pandoc_available("1.13.1")) stop("These vignettes assume pandoc version 1.13.1; older versions will not work.") rgl does something like that (but with a warning); I may change it to an error, since the older versions of pandoc really don't work.

Thanks a lot for the fast reply!

I see now, that rgl by itself seems to have a comparable problem: https://cran.r-project.org/web/checks/check_results_rgl.html

Your idea to first of all check the pandoc version seems to be good, but I don't know how to implement such a change to the usual build procedure.

At the moment I think I'm going to sit it out and wait for a fix instead of again spending hours just for the solaris setup.

I believe the problem is that those test systems don't have a current version of pandoc installed, so htmlwidgets falls back to an earlier version, which fails.

You may be able to avoid the Solaris problem by saying your package has a SystemRequirement of pandoc version >= 1.12.3, or (don't ask me how) checking for that version and not producing a document if it is not found.

I'm not sure what went wrong on OSX.

Hey rgl developers,

I'm using your excellent package to create some nice 3D plots in the vignette of my package recexcavaar (https://cran.r-project.org/web/packages/recexcavAAR/index.html + https://github.com/ISAAKiel/recexcavAAR). Unfortunately I get a nasty, almost undebuggable warning from three CRAN test systems: https://cran.r-project.org/web/checks/check_results_recexcavAAR.html

Quitting from lines 46-61 (recexcavAAR-vignette-1.Rmd)
Error: processing vignette 'recexcavAAR-vignette-1.Rmd' failed with diagnostics:
cannot open the connection

I'm not 100% sure it's a problem with rgl, but the mentioned lines relate to a rgl plot. Do you have an Idea what could cause this problem on solaris and osx?

Thanks a lot!
