Hi Adam, I suspect these two lines in your YAML header are causing trouble
> %\usepackage[utf8]{inputenc} > %\usepackage[table]{xcolor} - this is LaTeX code, which you shouldn't need if you're producing an HTML vignette. Also, with more recent versions of R markdown you should use knitr::rmarkdown rather than knitr::knitr as the vignette engine. For an HTML vignette, I'd expect your vignette field to look like this: vignette: > %\VignetteIndexEntry{DEVis} %\VignetteEngine{knitr::rmarkdown} %\VignetteEncoding{UTF-8} so try updating that block and see if that fixes it.
