groupedData
object is at least a data.frame and a
display formula that provides a grouping structure. In the
nfGroupedData
class there is only one level of grouping factors
and the response in the display formula is numeric. The
nfnGroupedData
class is a further refinement that specifies
that the primary covariate is numeric. At present we
are using old-style classes for groupedData
and the classes
that extend it."nfGroupedData"
, directly.
