A footnote, following an off-list exchange with Prof Ripley, is that I needed needed to have Suggested or other additional packages installed somewhere other than .Library .
"The following variables control checks for undeclared/unconditional use of other packages. They work by setting up a temporary library directory and setting .libPaths() to just that and .Library, so are only effective if additional packages are installed somewhere other than .Library.” [I am not sure of the source of this quote.] If vignettes make extensive use of Suggested packages, then exiting early from vignettes when access would otherwise be required to Suggested package [under knitr, one can use knitr::knit_exit()] can be an alternative to leaving out checking of vignettes in order to speed up initial testing. On MacOS Mojave with a bash shell env _R_CHECK_DEPENDS_ONLY_=true R CMD check qra_0.2.4.tar.gz works like a charm.

R does have hooks for this, I had these for a few years now: ~/.R/check.Renviron ~/.R/check.Renviron-Rdevel Again, might be worthwhile documenting it in the Inst+Admin manual (if it isn' already, I don't recall right now).
