tidy function

Tidy up a hyper2 object

Tidy up a hyper2 object by removing players about which we have no information

tidy(H)

Arguments

• H: A hyper2 object

Details

Function tidy(H) returns a hyper2 object mathematically identical to H but with unused players (that is, players that do not appear in any bracket) removed. Players about which H

is uninformative are removed from the pnames attribute.

Note that idiom pnames(H) <- foo can also be used to manipulate the pnames attribute.
