Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control. The R environment R is an integrated suite of software facilities for data manipulation, calculation and graphical display. R, like S, is designed around a true computer language, and it allows users to add additional functionality by defining new functions. Much of the system is itself written in the R dialect of S, which makes it easy for users to follow the algorithmic choices made. Advanced users can write C code to manipulate R objects directly.
Many users think of R as a statistics system.
We prefer to think of it of an environment within which statistical techniques are implemented. There are about eight packages supplied with the R distribution and many more are available through the CRAN family of Internet sites covering a very wide range of modern statistics. More information R comes with an FAQ list, and an introduction to the language and how to use R for doing statistical analysis and graphics in PDF and other formats. Return to GNU's home page .
