Unfortunately yes ... but I'd say this is a more general problem and
may also apply a to other user groups, so I would not hardcode a
--bioc exception into the code.
IMO R must be allowed to change, but if possible it should be easy to
protect yourself against changes when possible. I always considered
the parse&deparse behavior of Sweave a bug for which I had no simple
solution (and am somewhat surprised that there are people who think it
is a feature). So now that the bug is fixed, it would be natural for
me to make that available as default.
The unix way of solving something like that is having site-wide
configuration files which the sysadmin sets for all users. R has the
same concept, but R CMD check and build do not use it (to make the
process as portable as possible). That behavior is good as a default,
but we should allow users and sysadmins to override it, i.e., load
other configurations especially in R CMD build.
The basic concept was always that
1) The author runs R CMD build, and it is OK if that works only on the
author's machine, especially for vignettes. It is strange the
building vignettes finds and happily uses the local TeX
configuration including style and bibtes files, but ignores the
local R configuration.
2) Everybody, especially repositories, should be able to run R CMD
check on a package.
I'd propose to fix 1) in R 2.5.0, i.e., add an option --no-vanilla to
R CMD build such that local configurations are read.
