Examples

x <- SSBtoolsData("sprt_emp_geoHier")
s <- Hierarchy2Formula(x)
s
Formula2Hierarchy(s)

# Demonstrate Hierarchies2Formulas and problems 
hi <- FindHierarchies(SSBtoolsData("sprt_emp_withEU")[, c("geo", "eu", "age")])
hi
Hierarchies2Formulas(hi) # problematic formula since minus sign in coding 
AutoHierarchies(Hierarchies2Formulas(hi)) # Not same as hi because of problems 

# Change coding to avoid problems 
hi$age$mapsFrom <- gsub("-", "_", hi$age$mapsFrom)
hi
Hierarchies2Formulas(hi)
AutoHierarchies(Hierarchies2Formulas(hi))
