[R] How to count rows with a condition

I tried the code with unsorted ac_names column and found to be 
working.  So, couldn't identify exactly the problem.  If you can provide
 a subset of your dataset using ?dput(), then it would be much helpful. 

 dat3<-dat2[dat2[,1]%in%count(dat2[,1])$x[count(dat2[,1])[2]>5],] #data excluded 
dat4<-dat2[!dat2[,1]%in%count(dat2[,1])$x[count(dat2[,1])[2]>5],] #data included

Thanks for the first reply. 

Unfortunately, my list of different ac_names ist pretty long (about 1,000
different names). Is there a way, to sort them, count the quantity of each
name and exclude these rows, who exceed a particular limit?
