As I said that works nicely, however it turns out that I need to round
the result in a specific way, always round toward positive infinity, 
the matlab command `ceil' for example does this, I can't find anything
similar in the documentation. You recommend to use the R mailing list,
which I will do, but maybe you know it by heart?

Thanks and regards
