findGlobals in the codetools package can find all the functions that a function calls and you could construct a call graph from that by combining that with RGraphviz in Bioconductor.
For example, the proto package can automatically create a graph using RGraphviz showing the parent child relationship among the proto objects in a program. The graph at the top of the following page was generated like that from the program that you can view by clicking on the image: http://code.google.com/p/r-proto/wiki/Overview Its mainly applicable if you use proto but does illustrate the use of RGraphviz.
