R devel - Sep 2011 - Finding inter-function dependencies within a package

Hi,

I'd like to know which functions in a package call one specific function.
I think I've seen a tool for identifying such dependencies, but now I
can't
find it :-(
Searches of help and R site search for keywords like function, call, tree, 
depend haven't helped :-(

Can anyone point me in the right direction?

Thanks in advance,

Keith Jewell

Roxygen had the functionality to draw dependency graphs - but I think it has
been excluded in Roxygen2?

codetools::findGlobals could be used to do this.

Hi Keith

'foodweb' and friends in the 'mvbutils' package should do what
you're after.

For example, I just tried this on the 'debug' package:
> ff <- foodweb( where=asNamespace( 'debug'))
> # Now either just eyeball the dependency graph that 'foodweb'
produces, or more formally:
> callers.of( 'find.debug.HQ', ff) 
 [1] ".end.incarnation"          ".onLoad"                  
"bp"                        "check.legality"
 [5] "debug.eval.guts"           "debug.q"                  
"debug.Recall"              "debug.with"
 [9] "debug.within"              "dismiss.debug.window"     
"enact.command.r"           "eval.catching.errors"
[13] "evaluator"                 "find.active.control.frame"
"get.mtraced.callers"       "launch.debug.windows"
[17] "qqq"                       "set.global.debug.vars"    
"stepping"                  "try2"
