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

Hi developers,
[...]
Finally, if one want to install all packages including those in
'Suggests', one can do:

 biocLite("<pkg/group>", dependencies=c("Depends", "Suggests", "Imports"))
Note that currently, when I do:

  biocLite("<somepackage>", dependencies=TRUE)  # equivalent to the above

I end up with tons of packages that I'm not necessarily interested in.

This is because the behaviour of install.packages() (the backend of biocLite)
when "Suggests" is specified in the 'dependencies' argument is to follow
recursively the Suggests field. This is obviously the right thing to do for
the Depends and Imports fields but IMO the Suggests field should be treated
differently i.e. only packages *directly* suggested by <somepackage> should be
installed (+ the packages that those suggested packages depend on or import,
recursively, of course), but not the packages that the suggested packages
suggest :-P

It could be that this behaviour of install.packages() is partly responsible
of the too many installed packages that the user experiences sometimes...

Cheers,
H.

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):

POINT MADE?

PS. I'd like to suggest that is is checked as part of the initial
package review. DS.
