Gabor, maybe I am not understanding it right. I was thinking for example something like how a call to plot actually calls plot.zoo when zoo is loaded. And a specific call to plot.zoo would not work, etc. One would think that plot and plot.zoo are separate and that one could call the parent as well as the offsprings independently. But if this kind of setup is by design, than it's fine. Does that make sense?
