Thank you for verifying and digging deeper! I was making no assumption 
(yet) that kableExtra was the clear problem; while it does import 
grDevices and graphics, I wouldn’t expect a simple import to do it. 
Having said that, xml2 imports neither package directly. In fact, 
loading each of xml2’s imports does not trigger the error, so that 
suggests it’s either in xml2’s “./src/*“ files or linking against libxml2.

I apologize for the formatting issue. I use Markdown Here Revival for 
Thunderbird/Betterbird so that I can type in markdown and have it 
rendered into HTML. It surprises me only a little that the stripped-out 
html leaves a bit to be desired.
