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.
