This is not really a question about R... it is a question about databases
because similar divisions occur in every imperative programming language that
deals with databases. ODBC is a software layer that aims to create a uniform

I would recommend finding some tutorials on line in areas that you enjoy, read
http://r-bloggers.com every day, find introductory texts in the statistical
areas of interest, and study some texts on R programming. I really enjoyed The
Art of R Programming: A Tour of Statistical Software Design
Hi ,
As the OP was asking for examples , I would also recommend Modeling
Techniques in Predictive Analytics by Thomas Miller.
That book is full of examples + R scripts. Its on Amazon.

Since you're new to R, one of my tips would be to learn the class() and
str() functions. Many functions, such as plot, operate differently
depending on the class of data given to them, therefore it's very
important to know the classes of your data objects
