Package groupedHyperframe (v0.3.2.20251225) introduces a new S3 class 'groupedHyperframe', for grouped hyper data frame, which inherits from the class 'hyperframe' (Chapter 26). The derived class 'groupedHyperframe' has additional attributes

attr(,'group'), a one-sided formula of the (nested) grouping structure (Chapter 46).

Table 25.1 summarizes the S3 methods for the class 'groupedHyperframe' in package groupedHyperframe (v0.3.2.20251225), most of which are straightforward extensions of the S3 methods for the class 'hyperframe' (Listing 26.2, Table 26.1).
