Using reorder.factor from the stats package seems to work:
educ$ed <- reorder(educ$Education, sort(rep(1:4,5)))
levels(educ$Education)
[1] "CompletedHS" "IncompleteHS" "Uni1-3" "Uni4+"
levels(educ$ed)
[1] "IncompleteHS" "CompletedHS" "Uni1-3" "Uni4+"
xtabs(Count ~ ed + Age_Group, data=educ)
Age_Group
ed 25-34 35-44 45-54 55-64 >64
IncompleteHS 5416 5030 5777 7606 13746
CompletedHS 16431 1855 9435 8795 7558
Uni1-3 8555 5576 3124 2524 2503
Uni4+ 9771 7596 3904 3109 2483
