[R] Should I wrap more package examples in \dontrun{} ?

It was my understanding that package authors are responsible for not
breaking other CRAN packages without warning.  For example, before I
release a new version of plyr or ggplot2, I run R CMD check on every
package that depends on my package. I then let the maintainers know if
something is broken - sometimes it's because I introduced a bug, and
other times it's because I'm enforcing a stricter check than I did
previously
