[As I already posted, I don't think this is worth the effort, better
to just reinstall.]
But this coincides with work I've been doing on tools for package
dependency graphs. If you're curious, read on...
allDeps <- makeDepGraph(biocReposList(), type="source",
keep.builtin=TRUE, dosize=FALSE)
allDepsOnMe <- reverseEdgeDirections(allDeps)
needsMethods <- dijkstra.sp(allDepsOnMe, start="methods")
needsMethods <- needsMethods$distance[is.finite(needsMethods$distance)]
length(needsMethods)
[1] 514
table(needsMethods)
needsMethods
0 1 2 3
1 130 118 265
I won't spam the mailing list with the package names, but am happy to
make them available if anyone would really find it useful.
Bw,
+ seth
