These functions will aid in converting one education scheme into another. While you may attempt to go from a low level to a high (from 4 to 9), there is no way to actually do that in a consistent way that will correctly reflect the underlying data.
edu_reduce(x, from, to)
edu9_reduce(x, to = 4)character vector
factor level to transform from
factor level to transform to
factor
Always go from a higher level scheme to a lower one (currently from 9 to 4 only)
Specialized returns
edu_reduce - reduce with own to and from specification
edu9_reduce - directly reduce from 9 to 4
