Just so this is not misread - it's *not* possible to just hack your
vignette "product" files (PDF or HTML) into inst/doc and thinking
you're good. R keeps track of package vignettes in a "vignette
index", e.g.
> readRDS(system.file(package = "utils", "Meta", "vignette.rds"))
File Title PDF R Depends Keywords
1 Sweave.Rnw Sweave User Manual Sweave.pdf Sweave.R tools
which is created during 'R CMD build' by parsing and compiling the
vignettes
(https://github.com/wch/r-source/blob/tags/R-3-5-2/src/library/tools/R/build.R#L283-L393).
This vignette index is used to find package vignettes (e.g.
utils::vignette()) and build the HTML vignette index.
Also, one vignette source (e.g. Rnw, Rmd, ...) can only produce one
vignette product (PDF or HTML) in the vignette index. You can output
other files (e.g. image files) in a relative folder that the vignette
references, which is why for instance non-self-contained HTML files
work. Thus, one ad-hoc, not-so-nice hack that OP could do is to have
a single main vignette that produces and links to all child vignettes.
However, personally, I'd aim for using memoization/caching (to file)
such that each vignette can be compiled independently of the others
(and in any order), while still reusing intermediate
results/calculations produced by earlier vignettes.
