create Calagator::Event 1250466314 S4 Objects in R Roll back

description nil <p><i><b>S4 Objects in R</b></i></p> <p>This talk will review the goals of object oriented programming and how they are achieved in standard object oriented languages.  We will then look at how S4 objects work in R, how this is different from other languages, and how to use S4 objects to achieve standard object design patterns.  Finally, using production quality code, we will look at rewriting some functional code to use objects.</p> <p> <i>Wayne Haythorn</i> recently retired from a 30 year career in software design, during which he worked for organizations including NASA, the European Space Agency, National Weather Service, NOAA, Linsoft (Sweden), and Modern Terminals (Hong Kong).  You may remember him from last February's "What's New in Regression" presentation to the Portland R User Group.</p>
