Code tools for identifying which package A functions package B use?

Thanks Kasper, that seems to do it:

$ url=https://hedgehog.fhcrc.org/bioconductor/trunk/madman/Rpacks/codetoolsBioC
$ svn checkout --username readonly --password readonly $url
$ R CMD build codetoolsBioC
$ R CMD INSTALL codetoolsBioC
$ R

library("codetoolsBioC")
deps <- findExternalDeps("MASS")

attaching required packages 'MASS'
Loading required package: MASS

str(deps)

List of 4
 $ S4Classes: list()
 $ S4Methods:List of 1
  ..$ methods: chr "body<-"
 $ functions:List of 5
  ..$ base     : chr [1:248] "-" "!" "!=" "$" ...
  ..$ graphics : chr [1:16] "abline" "axis" "box" "frame" ...
  ..$ grDevices: chr [1:5] "dev.flush" "dev.hold" "nclass.FD" ...
  ..$ methods  : chr "new"
  ..$ stats    : chr [1:97] ".checkMFClasses" ".getXlevels" ...
 $ variables:List of 1
  ..$ base: chr [1:4] ".GlobalEnv" ".Machine" ".Options" "pi"

Great!

The best thing I have found is codetoolsBioC in the Bioconductor subversion
repository.

Best,
Kasper

Hi,

I'd like to list all package PkgA functions that another package PkgB
use via Depends or Imports (ignoring Suggests for simplicity).  As
long as PkgB uses importFrom("PkgA", ...) it's just a matter of
parsing the NAMESPACE file or inspecting
asNamespace("PkgB")$.__NAMESPACE__.$imports.  However, what can be
done in case PkgB uses import("PkgA")?  Is there a function/package
already available for this?

Thanks,

Henrik
