Lynda.com provides both a free intro status and a monthly-fee subscription to a vast library of professionally-done videos on a wide variety of computer topics -- from intro programming to R programming. Take a look at the catalog and notice the times and topics of the available courses.
Of course (pun intended), the web has info on a wide variety of tutorials, books, etc. that are often free. However, if you are "determined to learn this," go for quality products!
