Drug developers use it to evaluate clinical trials and determine which medications are safe and effective; archaeologists use it to sift through mounds of artifacts and track the spread of ancient civilizations; and actuaries use it to assess financial risks and keep economies running smoothly. In The Art of R Programming , veteran author Norman Matloff takes readers on a guided tour of this powerful language, from basic object types and data structures to graphing, parallel processing, and much more.

This has been observed over the years of the epidemic and has been confirmed by three randomized controlled trials concluded in 2005-2006.The results have led to the conclusion that male circumcision is an effective risk-reduction measure for men and should be used in addition to other known strategies for the prevention of heterosexually acquired infection.
