The first thing is to get the correct repositories repos = BiocManager::repositories()
(maybe trim the experiment and annotation repos from this). I also tried pkgDepTools::makeDepGraph() but it took so long that I moved on... it has an option 'keep.builtin' which might include Matrix. There is also BiocPkgTools::buildPkgDependencyDataFrame() & friends, but this seems to build dependencies within a single repository... The building block for a solution is `tools::package_dependencies()`, and I can confirm that "Matrix" _is_ a dependency db = available.packages(repos = BiocManager::repositories()) revdeps <- tools::package_dependencies("GenomicScores", db, recursive = TRUE) "Matrix" %in% revdeps[[1]] ## [1] TRUE so I'll leave the clever recursive or graph-based algorithm up to you, to report back to the mailing list? For what it's worth I think the last time this came up Martin Maechler pointed to a function in base R (probably the tools package) that implements this, too...?
