[Bioc-devel] Upcoming release: *Please* revise your Depends and Suggests of DESCRIPTION

[Henrik Bengtsson]

Hi *all* package developers

for the upcoming Bioc release, as a developer, could you please revise
what packages you put under 'Depends' in your DESCRIPTION files.

In many cases packages listed there are only used occationally in a
few rarely called functions.  In such cases it is recommended to put
such packages under 'Suggests' instead and use require("<pkg>") where
ever they are needed.   This will decrease the download/installation
footprint.

Without picking on a particular package (I've used a different package
before), here is an illustrative example involving several packages
with large package footprints:

In order to use the runBioHMM() segmentation method in the snapCGH package:

Package: snapCGH
Depends: limma, tilingArray, DNAcopy, GLAD, cluster, methods, aCGH
Suggests:
Imports:

this is what you need to download and install (illustrated package by package):
