[BioC] Gene Ontology: filtering out most informative terms from a list of GO terms

Hello everyone,

I wish to filter a list of Gene Ontology terms for the tip terms (most 
informative GO level) i.e. removing all GO terms which have more general 
ancestors in the GO hierarchy, also contained in this list. In the graph 
view this would mean, that after  having applied the filter, there 
should be no GO terms in the graph which have  more informative children 
and successors.
I had a look at the different packages dealing with the GO in 
bioconductor but haven´t found a suitable one so far. Is there by chance 
anybody, who knows  a package in bioconductor, which can be used to 
tackle this problem?

Thanks a lot for your time,
