[Bioc-devel] r+w permissions in release branches

[Wolfgang Huber]

Hi Julian

what if two Bioc packages require different version of the ‘same’ CRAN package?
AfaIu, the infrastructure is not designed to deal with multiple versions of a package.

Nor would I as a user expect to have less-than-the-most recent versions of CRAN packages in my library just because some other package says so…
 
Just to throw in another, and probably silly suggestion: the Bioconductor repository could keep ‘snapshots’ of CRAN packages compatible with each release, but they would have to be name-mangled in some way. The potential for confusion is enormous.

	Best wishes
	Wolfgang

See e.g. the 'devtools::install_version' function for installing older packages from the CRAN archive.  This may have drawbacks for binary or compiled packages though.
