gsigetBalStruct | R Documentation |
Parses the expressions for the balance functions.
gsi.getBalStruct(descr,names,allowMinus=FALSE,allowOne=FALSE)
descr |
the expression |
names |
character: the variables in the dataset |
allowMinus |
whether to allow for |
allowOne |
whether to allow |
These functions will not be usually called on themselves, but
through their wrappers, mainly balanceBase
.
provides a list of pairs giving the components in the Numerator and the Denominator of the balances.
It is better not to use gsi.* functions directly since they are internal functions of the package. Use their wrappers.
