There are some important differences, but much of the code written for S runs unaltered. The project was conceived in 1992, with an initial version released in 1995 and a stable beta version in 2000.
R is easily extensible through functions and extensions, and the R community is noted for its active contributions in terms of packages. Many of R’s standard functions are written in R itself, which makes it easy for users to follow the algorithmic choices made. R is highly extensible through the use of user-submitted packages for specific functions or specific areas of study. Another strength of R is static graphics, which can produce publication-quality graphs, including mathematical symbols. Dynamic and interactive graphics are available through additional packages. This calculation is interpreted as the sum of two single-element vectors, resulting in a single-element vector.
The scalar data type was never a data structure of R. Instead, a scalar is represented as a vector with length one. The R packaging system is also used by researchers to create compendia to organise research data, code and report files in a systematic way for sharing and public archiving. R has been applied and for which packages are available. R has also been identified by the FDA as suitable for interpreting data from clinical research.
R packages, R-related software, and projects. R-Forge also hosts many unpublished beta packages, and development versions of CRAN packages. A list of changes in R releases is maintained in various “news” files at CRAN. Some highlights are listed below for several major releases. The mailing lists commenced on April 1, 1997.
