Dear Spencer, I wasn't aware of getFunctions(), though I've now taken a look at it. It's pretty similar to listFunctions() (from my email to the list), except that getFunctions() uses exists() rather than is.function() to test whether an object is a function. There must be a reason for this, but I can't think what it is, since in both cases the vector of object names shouldn't include nonexistent objects.
