FWIW I think it was a red herring - after bugfixes to the package and installing (unstated*) dependencies it works (possibly use of require instead of library in the vignette might help - I don't know what the best practice is).

There are examples on CRAN of packages which cannot re-make their vignettes without external files (e.g. LaTeX style files), or take hours (literally) to run the code. The source package should contain the PDF versions of the vignettes as made by the author.

> What the people who do the CRAN package checks do get unhappy about are packages which fail running the R code in their vignettes, since this often indicates a problem in the package which is not exercised by the examples nor tests. This gives a warning, as you will see in quite a few CRAN package checks.
In the case of TripleR R CMD check failed (i.e. error code != 0) because of the vignette.
* - which reminds me -- what is the correct place to list vignette dependencies? "Suggests:" ?
R CMD check simply fails in the vignette build when vignetts use unstated dependencies [via library()] - there is no explicit warning/error by check itself.
