R OOP – a little privacy please?

August 23, 2014
By

As of late, I’ve been making heavy use of Reference Classes in R. They are easier for me to wrap my mind around since they adopt a usage style more like “traditional” OOP languages like Java. Primarily, object methods are part of the class definition and accessed via the instantiated object. For instance: With S3/S4 classes, you...

August 21, 2014

It’s...
