I have a package with more than 100 datasets, each of which has an
\examples{} section. On the plus side, these example test the "R
ecosystem" to make sure that everything is working (both my package and
others' packages). On the down side, changes in this ecosystem have caused
repeated NOTEs and WARNINGs from CRAN.
As a commentary on one recent R-help discussion, none of the code breakages
have been caused by use of ":::". All of the problems have been caused by
(1) Changes in "stable" packages and (2) changing CRAN requirements (3)
changes in "beta" packages. In roughly that order.
In the interest of long-term package stability I'm thinking about wrapping
more of the examples in my package in \dontrun{}. Especially the parts
that depend on other packages.
I'm interested to know how other package developers approach this problem.
