S-PLUS is a commercial implementation of theS programming language sold byTIBCO Software Inc.
It features object-oriented programming capabilities and advanced analytical algorithms. Its statistical analysis capabilities are commonly used byeconometricians. The S-PLUS FinMetrics software package was developed for econometric time series analysis.[1]
Due to the increasing popularity of the open source S successorR, TIBCO Software released theTIBCO Enterprise Runtime for R (TERR) as an alternative R interpreter.[2] It is available onWindows andUNIX operating systems.[3]
In 1988, S-PLUS was first developed and released by a Seattle-based start-up company called Statistical Sciences, Inc.[4] The company's founder and sole owner was R. Douglas Martin, professor of statistics at theUniversity of Washington, Seattle. Martin originally learned S while working at Bell Laboratories, where the S language was originally developed.[1] At the time of its release, S-PLUS was one of the first examples of software that implemented algorithms forgeneralized linear models, second toGLIM.[5]
Statistical Sciences acquired the exclusive license to distribute S and merged with MathSoft in 1993, becoming the firm's Data Analysis Products Division (DAPD).[6]
In 1995, S-PLUS 3.3 forWindows 95/NT was released, including the Matrix library, command history capability, and Trellis graphics. This was followed by the release of S-PLUS 3.4 for UNIX in 1996. This version included anon-linear mixed-effects modeling library, hexagonal binning, and cluster methods. S-PLUS 4 was released for Windows in 1997, with features such as an updated GUI, integration withExcel, and editable graphics. S-PLUS 4.5 for Windows in 1998, withScatterplot brushing, and the ability to create S-PLUS graphs from withinExcel &SPSS. The software also became available for Linux &Solaris.
In 1999, S-PLUS 5 was released for Solaris, Linux,HP-UX,AIX,IRIX, andDEC Alpha. S-PLUS 2000 for Windows. nlme 3.3,quality control charting, and new commands for data manipulation. This was followed by S-PLUS 6 forLinux/Unix in 2000. This version had a Java-based GUI, Graphlets, survival5, and a library for handling missing data.
In 2001, MathSoft sold its Cambridge-based Engineering and Education Products Division (EEPD), was renamed Insightful Corporation, and moved headquarters to Seattle. This essentially reversed the previous merger between MathSoft and Statistical Sciences, Inc.[7] S-PLUS Analytic Server 2.0. S-PLUS 6 was released for Windows in 2001.
In 2002, StatServer 6 was released and the student edition of S-PLUS became free. S-PLUS 6.2 was released and ported to AIX. In 2004, Insightful purchased the S language fromLucent Technologies for $2 million, and released S+ArrayAnalyzer 2.0.
S-PLUS 7.0 was released in 2005, including the BigData library for working with larger-than-memory data sets and the S-PLUS Workbench (Eclipse development tool). Insightful Miner 7.0 was also released. In 2007, S-PLUS 8 was released with a new package system, language extensions forR package compatibility, and a workbench debugger.
TIBCO acquired Insightful Corporation for $25 million in 2008.[8]
