Hierarchy2Formula

Description

Conversion between to-from coded hierarchy and formulas written with =, - and +.

Usage

Hierarchy2Formula(
  x,
  hierarchyVarNames = c(mapsFrom = "mapsFrom", mapsTo = "mapsTo", sign = "sign", level =
    "level")
)

Formula2Hierarchy(s)

Hierarchies2Formulas(x, ...)

Arguments

x

Data frame with to-from coded hierarchy

hierarchyVarNames

Variable names in the hierarchy tables as in HierarchyFix.

s

Character vector of formulas written with =, - and +.

...

Extra parameters. Only hierarchyVarNames is relevant.

Value

See Arguments

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))
