Editing a class design object is seldom useful.
It is discouraged to edit design objects from within R. Users should export the design and re-import it after adding response data.
Nevertheless, it is possible to add response values by adding numeric columns to
the design with the editor (never edit factors!),
and users will have to attach the responses added
to an edited design to their original design afterwards, using e.g. the
Modify design -> Add response variables ...
menu, providing the edited data set as the R object that contains the responses.
