Maybe support LinkingTo as well?

[eddelbuettel]

When I build (much simpler) dependencies via the tools package, I follow their usual pattern of (and here I quote from the help for tools::package_dependencies)

   which: a character vector listing the types of dependencies, a
          subset of ‘c("Depends", "Imports", "LinkingTo", "Suggests",
          "Enhances")’.  Character string ‘"all"’ is shorthand for that
          vector, character string ‘"most"’ for the same vector without
          ‘"Enhances"’.

and tend to pick either 'all' or 'most' -- or just stick with the default value of the more explicit narrower set of c("Depends", "Imports", "LinkingTo").

For packages like Rcpp and BH that matters a lot as most of the 'edges' in the graph are compile-time via LinkingTo, rather than via depended-upon or imported R code.

That said, awesome looking package :) This will be nice to have around.

Ah yes; that's important thanks. Full LinkingTo support is now on GitHub and will be on CRAN in the next release in a few weeks.

[eddelbuettel]

Nice. Thank you.

Can your extractors also combine, ie do what CRAN does and use

  Depends OR Imports OR LinkingTo 

all of which are hard dependencies?

[ikosmidis]

Yes. I wrote the plot method for summary to be totally agnostic to the statistic to be bar-plotted. So, (using the development version for now) you can do

library("cranly")
package_db <- clean_CRAN_db()
package_network <- build_network(package_db)
package_summaries <- summary(package_network, advanced = FALSE)
package_summaries$n_hard <- with(package_summaries, { 
                                        n_linked_by + n_depended_by + n_imported_by
})
plot(package_summaries, top = 30, according_to = "n_hard")

Is this what you are after?

[eddelbuettel]

Excellent -- that corresponds to the result we get via the pagerank package by @andrie. Maybe add a filter to remove R Base / R Recommended packages?

[ikosmidis]

Yes. Subsetting according to base is already in my todo for next release with moderate priority. Opened a new issue on this #2.

[ikosmidis]

Done in #2
