For S3 objects:
?base::Ops
http://n4.nabble.com/Operator-overloading-td854452.html#a854452
http://n4.nabble.com/Overloading-td850827.html#a850828
For S4 objects:
?methods::Ops
http://n4.nabble.com/How-to-define-new-operators-td974842.html#a974842
A good resource for reading material on S4 classes, which are more formally
defined than S3 classes, can be found in the R wiki:
http://rwiki.sciviews.org/doku.php?id=tips:classes-s4
Hope this can get you started!
