[R] get the value of a biplane

[Jeff Newmiller]

Well, then I will hedge by saying that IN MY OPINION it is an error, because when it isn't exported the arguments not specified in the generic cannot be visible for argument completion in editors.  The predict.lm function specifies new data with the newdata argument, while the predict.bs function specifies it with the newx argument. Invoking with the generic is supposed be useful when trying out a variety of models, but being unable to generically specify a data frame (due to the inconsistent naming) blows that strategy to pieces anyway so you might as well be able to call the functions explicitly.
