[R-pkg-devel] Package dependency graphs of packages in development (local)

[Gábor Csárdi]

You can do something like this with https://github.com/r-lib/pkgdepends:

pr <- pkgdepends::remotes()$new("local::.", library = tempfile())
#> ℹ Creating library directory:
`/var/folders/59/0gkmw1yj2w7bf2dfc3jznv5w0000gn/T//Rtmpo5NL9R/filee95427c73f55`

pr$solve()
#> ℹ Checking for package metadata updates
#> ✔ All 10 metadata files are current.
#> ✔ Using session cached package metadata
#> ✔ Using cached package metadata

#>   standard:

And the `deps` column there shows the direct dependencies of the dependencies:
