The nice thing with the (not so nice) function I ended up with is that it
would be fairly easy to use any other function, such as rmarkdown::render
instead of knitr::pandoc. As for me, as I already use knitr (obviously) to
knit, and pandoc is also installed on my system, it makes more sense to use
what's available! Or maybe I'm missing the obvious: is there a strong
argument in favor of rmarkdown::render instead of knitr::pandoc?
Mathieu.
