Introduction to R

R is a general-purpose computer language. It is similar to S
language, and much code written for S run unalterd under R. Its
particular strength is in statistical, graphical capabilities. You
can also do simple simulation with R. R is *free*: it's nothing
to do with *free* as in beer. You get *free*dom to do
whatever with R! So once you learn R, R will not disappear like a lot
of other commercial products.

Some users think of R as a statistics system, but it is more of an
environement within which statistics can be implemented. Capability
of R can be easily extended by *packages*. There are many
user-contributed packages which convers a wide range of **modern
statistics**. These extra packages can be downloaded from
The Comprehensive R Archive Network
(cran).

R runs on Linux, Mac, and Windows.
