Hi,
Terry Therneau's question about package development reminded me of a
different issue. I maintain several packages along with a repository for
them at "http://bioinformatics.mdanderson.org/OOMPA/";. Several people
are working on adding features or testing the packages. So, I often want
to have both the latest official release and the currently testable
build of the package available in the repository. I tried putting both
versions in the same repository, but this leads to a problem for some of
the testers, who are not familiar with the intricacies of building
packages. (Thus, I cannot just tell them to get the source tarball and
compile it; they will have no clue as to what I am talking about. And
their Windows machines will not have the required tools installed in any
event.)
The underlying problem is that when you run the command
> install.packages(repos="http://bioinformatics.mdanderson.org/OOMPA";)
inside the R Windows GUI, the selection box that appears only lists the
name of the package, _not_ the version number. Thus, the testers cannot
tell which of two packages with the same name should be installed.
Is there any way around this problem other than to maintain two
different repositories?
available.packages() reports version numbers, e.g.
available.packages(contrib.url("http://bioinformatics.mdanderson.org/OOMPA";))
You'll need to write a user interface to make use of this.
