value

A two element vector of which the first element is the name of the variable and the second the column name in the Data slot of the object.

Details

The Xpose variable definitions are used to map particular variable types to column names in the data.frame in the Data slot of the "xpose.data" object. The single-valued Xpose variable definitions are: id, idlab, idv, occ, dv, pred, ipred, iwres, res. The (potentially) vector-valued Xpose variable definitions are: parms, covariates, ranpar, tvparms (parameters, covariates, random effects parameters=etas, typical value parameters). The default values of these can be found in the createXposeClasses function.

Value

Returns a string with the name of the data variable defined as the Xpose data variable.
