The Writing R Extensions manual describes vignette support in R, but R 
allows contributed packages (like knitr, rmarkdown, R.rsp) to handle 
vignettes.  WRE explains enough to write such a package, but it's up to 
their authors to document how to use them, so "complete documentation" 
is spread out all over the place.  As with any documentation, there are 
probably errors and omissions.
