⚠️There's a newer version (1.26.0) of this package.Take me there.

R.oo (version 1.24.0)

R Object-Oriented Programming with or without References

Description

Methods and classes for object-oriented programming in R with or without references. Large effort has been made on making definition of methods as simple as possible with a minimum of maintenance for package developers. The package has been developed since 2001 and is now considered very stable. This is a cross-platform package implemented in pure R that defines standard S3 classes without any tricks.
