Problems with RMarkdown & HTMLWidgets
OK, so in working on various RMarkdown stuff, I‘ve just run across a problem with it no longer rendering HTMLWidget stuff in the recent upgrade. So if you use something like
leaflet in your
xaringan presentation, it will show you the raw
output instead of the actual widget. This is not an easy one to track down online because the RMarkdown & Xaringan Github sites do not address it. So I thought I would insert a thing here so I can find it next time I need it.
As it turns out, we need to set an option in the setup chunck as follows:
options(htmltools.preserve.raw = FALSE)
This will fix things until RStudio fixes the markdown problems and the world can get back to normal.
