[Bioc-devel] how to trace 'Matrix' as package dependency for 'GenomicScores'

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...?

     hi,
     
     when i load the package 'GenomicScores' in a clean session i see thorugh
     the 'sessionInfo()' that the package 'Matrix' is listed under "loaded
     via a namespace (and not attached)".
     
     i'd like to know what is the dependency that 'GenomicsScores' has that
     ends up requiring the package 'Matrix'.
     
     i've tried using the package 'pkgDepTools' without success, because the
     dependency graph does not list any path from 'GenomicScores' to 'Matrix'.
     
     i've been manually browsing the Bioc website and, unless i've overlooked
     something, the only association with 'Matrix' i could find is that
     'S4Vectors' and 'GenomicRanges', which are required by 'GenomicScores',
     list 'Matrix' in the 'Suggests' field, but my understanding is that
     those packages are not required and should not be loaded.
     
     so, is there any way in which i can figure out what of the
     'GenomicScores' dependencies leads to loading the package 'Matrix'?
     
     here are the depends, import and suggests fields from 'GenomicScores':
     
     Depends: R (>= 3.5), S4Vectors (>= 0.7.21), GenomicRanges, methods,
              BiocGenerics (>= 0.13.8)

              BSgenome, GenomeInfoDb, AnnotationHub, shiny, shinyjs,
     	DT, shinycustomloader, rtracklayer, data.table, shinythemes
     Suggests: BiocStyle, knitr, rmarkdown, BSgenome.Hsapiens.UCSC.hg19,
              phastCons100way.UCSC.hg19, MafDb.1Kgenomes.phase1.hs37d5,
