[Bioc-devel] Pandoc issues

[Vladimir Kiselev]

Hi Herve,

Thanks for your reply! scmap::getSankey() didn't really work in the
release, so I switched it off quite long ago by setting `eval = FALSE`.

Regarding rmarkdown: I remember when I updated Pandoc I got a different
error from rmarkdown, then I googled it and found that it was related to
the changes in the new version of Pandoc (I can't find the link now....).
The rmarkdown maintainer said he'd fixed it in the latest version which is
not the release version it. I have installed rmarkdown from github (at the
moment I have 1.8.3) and there was no error. They probably forgot to update
SystemRequirements.

So, I suppose updating Pandoc on your side won't solve the problem
completely and we will need to wait until the new version of rmarkdown is
pushed to CRAN. At the moment I can probably switch Sankey diagrams off in
my vignette. The problem is I have just significantly updated it and these
diagrams are quite important now.

Cheers,
Vlad
