Learn R Programming

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

R.oo (version 1.1.0)

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 maintainance for package developers. For example, generic functions are created automatically, if missing, and name conflict are automatically solved, if possible. The method setMethodS3() is a good start for those who in the future want to migrate to S4. The package has been developed since 2001 and is now considered very stable.
