[Bioc-devel] library checking: question on require/depends

[Laurent Gautier]

Adding it in "Suggests" will keep R CMD check happy, as Sean told it.

One question, still:
Are you using the those packages in examples ? In that case, using a
smaller dataset might be a good idea.
If there is not any suitable smaller dataset currently avalaible, it
could be nice to create a demo-oriented one, with one chromosome for
example. This could also be used by other packages needing full
genome.
