R is open source software for statistical analysis. Being open source (Gnu GPL licensed) doesn't just mean that the software is free. It means that you can use it for a variety of applications, and install it virtually anywhere you'd like, without any restrictions. Open source also means that the code for all statistical procedures and analysis can be independently checked and verified. The activity community of R users is constantly developing new add-on packages that use the latest techniques, which you are free to do as well. And, being free, you can always have access to the latest version of the software, no matter where you are.
R is also a programming language, which makes it easy to document, reuse and reproduce all the steps of your statistical analysis.

describing a function
• example(function) provides detailed examples
• for help on a whole package, try library(help=packagename)
• apropos and help.search (deep vs. fuzzy search, respectively)
These are some miscellaneous useful and interesting links that may help you accomplish some specific tasks in R.
