R devel - Jan 2018 - How to address the following: CRAN packages not using Suggests conditionally

Re-sending, since I forgot to include the list, sorry. I'm including
r-package-devel too this time, as it seems more appropriate for this list.

Thanks a lot, I?aki, this is a perfect solution! I already implemented 
it and it works great. I'll wait for 2 more days before I submit the 
revised package to CRAN - in order to give others to comment on it.

Best regards,
Ulrich

It's very easy for 'pictures of code' (unevaluated code chunks in 
vignettes) to drift from the actual implementation. So I'd really 
encourage your conditional evaluation to be as narrow as possible -- 
during CRAN or even CRAN fedora checks. Certainly trying to use 
uninstalled Suggest'ed packages in vignettes should provide an error 
message that is informative to users. Presumably the developer or user 
intends actually to execute the code, and needs to struggle through 
whatever issues come up. I'm not sure whether my comments are consistent 
with Writing R Extensions or not.

There is a fundamental tension between the CRAN and Bioconductor release 
models. The Bioconductor 'devel' package repositories and nightly builds
are meant to be a place where new features and breaking changes can be 
introduced and problems resolved before being exposed to general users 
as a stable 'release' branch, once every six months. This means that the
Bioconductor devel branch periodically (as recently and I suspect over 
the next several days) contains considerable carnage that propagates to 
CRAN devel builds, creating additional work for CRAN maintainers.
