https://github.com/r-lib/pkgapi has map_package() which will list all

Thanks, this gives a grepable character vector in map$calls$to from which
I can search for "A::" among the namespaces listed. The function returns
S3 methods (I think - some are written in full in the "B" code). I'm not
sure about S4 methods or class definitions. However, I'm much further
forward, again, thanks!

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
