Patrick Hausmann was so kind to make me aware of Dr. Dirk Enzmann  
website <http://www2.jura.uni-hamburg.de/instkrim/kriminologie/ 
Mitarbeiter/Enzmann/Software/Enzmann_Software.html> it hold a quite  
beautiful function, freq [http://www2.jura.uni-hamburg.de/instkrim/ 
kriminologie/Mitarbeiter/Enzmann/Software/freq.r], that almost does  
the trick. Though there?s still the problem of all the NAs being  
pilled together so the different missing aren?t shown separately  
under ?Percent?.
Though I think it's should be possible to modify it ? Has anyone  
messed around with this function or have a similar function that  
distinguish between valid and missing answers overall and then make a  
percent with in the valid answers and a percent over all?

I promise not to bother the list anymore whit this. Tomorrow I will  
sit down and try to figure it out.

Thanks aging for all the help.
