It consists of a rich and enhanced language plus a run-time environment with graphics, access to certain system functions, a debugger and the ability to run programs stored in script files.
The design of the language has been inspired from Scheme and S. Whereas the resulting language is very similar in appearance to S, the underlying implementation and semantics are derived from Scheme.
The core of R is an interpreted computer language which allows branching and looping as well as modular programming using functions. Most of the user-visible functions in R are written in R.
It is possible for the user to interface to procedures written in the C, C++, or FORTRAN languages for efficiency. The R distribution contains functionality for a large number of statistical procedures.
Among these are: linear and generalized linear models, nonlinear regression models, time series analysis, classical parametric and nonparametric tests, clustering and smoothing.
There is also a large set of functions which provide a flexible graphical environment for creating various kinds of data presentations.
R is being developed for the Unix, Windows and Mac families of operating systems.
News in the current The R Project by The R Core Team version:
• The PCRE library has been updated to version 8. 00.
• R CMD INSTALL has new options --no-R, --no-libs, --no-data, --no-help, --no-demo, --no-exec, and --no-inst to suppress installation of the specified part of the package. These are intended for special purposes (e. g. building a database of help pages without fully installing all packages).
• The documented line-length limit of 4095 bytes when reading from the console now also applies also to parse(file="") (which previously had a limit of around 1024 bytes).
• A Bioconductor mirror can be set for use by setRepositories() via the option "BioC_mirror", e. g. the European mirror can be selected by options(BioC_mirror="http://bioconductor. statistik. tu-dortmund. de")
• Double-clicking in a tk_select. list() list box now selects the item and closes the list box (as happens on the Windows select. list() widget).
• The 'extended' argument is deprecated in strsplit(), grep(), grepl(), sub(), gsub(), regexpr() and gregexpr() (not just the value extended = FALSE) and will be removed in R 2. 11. 0.
• trigamma(x) and other psigamma(x, n) calls are now accurate for very large abs(x).
• [g]sub(perl=FALSE, fixed=FALSE) could use excessive stack space when used with a very long vector containing some non-ASCII strings.
• The default method of weighted. mean(na. rm = TRUE) did not omit weights for NA observations in 2. 10. 0.
