[R-pkg-devel] Analysing namespace reverse dependencies

https://github.com/r-lib/pkgapi has map_package() which will list all
the functions of a package, where they were defined, and also all
function calls, internal ones and calls to external packages as well:

map <- pkgapi::map_package("~/works/processx")
names(map)
#> [1] "name"    "exports" "defs"    "calls"

head(map$calls, 3)
#>               file        from                 to type
#> 1 R/aaassertthat.R assert_that base::parent.frame call
#> 2 R/aaassertthat.R assert_that   processx::see_if call
#> 3 R/aaassertthat.R assert_that       base::return call
#>   line1 line2 col1 col2          str
#> 1     2     2   36   47 parent.frame
#> 2     3     3   10   15       see_if
#> 3     4     4   12   17       return

Because of the dynamic nature of the language, some false negatives,
and maybe even false positives might happen.

Hi,

Is anyone aware of tools permitting the listing of functions in the
namespace of package A used by package B when package B declares that it
depends on A, suggests A, or imports(A) without specifying the functions
from A that B is using? If B imports functions from A, and uses
importsFrom() in its NAMESPACE, the information can be recovered by
inspecting its NAMESPACE file (assuming that the entries are correct), but
not otherwise.

Grateful for any pointers,

Roger
