Not precisely an answer to your question but here are some OO R links that I have collected over time. Not sure if all these links still work. <a href="http://www.stat.wisc.edu/~st771-1/slides/wk2-4.pdf">Bates</a> | <a href="http://www.maths.lth.se/help/R/">Bengtsson</a> | <a href="http://cm.bell-labs.com/cm/ms/departments/sia/Sbook/">Chambers</a> | <a href="http://biosun1.harvard.edu/courses/individual/bio271/">Gentleman</a> | <a href="http://faculty.washington.edu/tlumley/Rcourse/objects.pdf">Lumley</a> | <a href="http://maths.newcastle.edu.au/~rking/R/devel/03a/0969.html">Symth</a> --- Date: Wed, 25 Feb 2004 12:42:13 -0800 From: Vadim Ogranovich <vograno at evafunds.com> To: R Help List <r-help at stat.math.ethz.ch> Subject: [R] books: "Programming with Data: A Guide to the S Language" vs." S Programming" Hi, Could someone please compare "Programming with Data: A Guide to the S Language" by J. Chambers and " S Programming" by W. Venables and B. Ripley? Ideally, I need a "guide" for writing R OO-style packages that intensively interact with C/C++ libraries. The specific project I have in mind is to write a thin and limited DB-connectivity package that would interact with Oracle via its OCCI interface (it's an intention subject to time availability and project complexity). If you've been there or somehow think this is a daunting task I'd love to hear from you. Thanks, Vadim
