Methods that simplify the setup of S3 generic functions and S3 methods.
Major effort has been made in making definition of methods as simple as
possible with a minimum of maintenance for package developers. For
example, generic functions are created automatically, if missing, and
naming conflict are automatically solved, if possible. The method
setMethodS3() is a good start for those who in the future want to migrate
to S4. This is a cross-platform package implemented in pure R and
generates standard S3
methods.
