[R-pkg-devel] Disable a particular knitr vignette
As a workaround, until resolved, you could precompile your vignette
into a PDF and then use the 'R.rsp::asis' vignette engine
(%\VignetteEngine{R.rsp::asis} etc) to include it as a static PDF.
This is described in the vignettes
(https://cran.r-project.org/package=R.rsp).

Hi everyone, I have a JSS vignette based on the rticles package. It was compiling just fine until rticles v0.5 for some reason started requiring pandoc v2.x for such a document class, and failing otherwise. Due to this requirement, Windows machines on CRAN show a nasty WARN, because they still have pandoc v1.x. It is painful for Uwe to install pandoc v2.x there, so I was wondering whether there's any easy mechanism to just disable a particular vignette based on some condition (in this case, it would be "we are on CRAN, this is Windows and the pandoc version is < 2"; this is easy to test). I tried putting a condition for the output format in the YAML header and it works, i.e.: output: if (cond) rticles::jss_article else rmarkdown::pdf_document But rmarkdown::pdf_document fails to compile, because the JSS class has many custom macros. I tried also putting a NULL or a NA there, and it doesn't work. Does any knitr ninja here know if there's some easy trick to do this and make Uwe's life easier? Some "NULL" document format? Regards, I?aki
