S-PLUS is an enhanced statistical program from Insightful, Inc., based on the popular statistical package, "S".
Faculty, staff, and students at the University of Virginia may access S-PLUS in three different ways: in the ITC Labs, on Unix workstations, or on your own machine.
Our site license for S-PLUS requires two different types of installation depending on whether you are UVa faculty and staff or a UVa student. UVa faculty and staff should install the network version of S-PLUS on UVA-owned computers on-grounds. Students must use the personal copy (standalone) of the software which may be installed either on- or off-grounds on their personally-owned computer. On the Windows platform we are currently distributing version 8.0 of both the network version and th e standalone version.
By special request, faculty and staff can get a copy of the "standalone" version of S-PLUS for installation off-grounds or on a personally-owned computer. This restriction is necessary because we have a limited number of licenses for faculty and staff use, most of which are dedicated to enabling the simultaneous connections for the network version used both by individual faculty and staff and by the computers in the ITC public computing facilities and ITC Unix servers.
The software vendor, Insightful, Inc., grants us an unlimited number of student copies based on the number of faculty/staff licenses we've purchased. In addition, the standalone version has an automatic expiration one year after installation.
In all ITC computer labs and classrooms, S-PLUS 8.0 for Windows is installed on all Microsoft Windows machines. For a list of all labs and locations, visit the ITC Labs and Classrooms webpage.
S-PLUS 8.0 for Unix is available at UVa on the Sun, AIX and Linux platforms. It may be accessed by typing "splus" at the unix prompt. S-PLUS 8.0 can be run either in a standard terminal session or in an x-windowed environment by typing "splus -g". It will take several minutes before the GUI is displayed on your screen.
Mounting ITC common directories on an on-grounds Linux machine
S-PLUS and other ITC-licensed software, such as Matlab, MAPLE, Mathematica, and IDL are on a server that handles any license restrictions (i.e.,. the number of simultaneous connections allowed). To be able to mount the file systems /common and /linux from jeeves.itc.Virginia.EDU, read the discussion at http://www.itc.virginia.edu/desktop/linux/mount.html.
3. Acquire a copy for your own computer
Faculty/Staff
All faculty and staff affiliated with the University of Virginia should use the network version of S-PLUS on UVA-owned computers on-grounds. This is a complete installation of S-PLUS that checks out a license from a license manager running on a central ITC server.
The Network version of S-PLUS for Windows can be obtained by download free of charge from the ITC licensing database. Instructions on First-time Installation of the Network Windows S-PLUS software and configuring your local workstation to communicate with the license manager are available online.
Faculty and staff may access S-PLUS for Linux on-grounds by mounting ITC common directories.
Students
Students must use the personal copy (standalone) of the software which may be installed either on- or off-grounds. The standalone license version of S-PLUS version 8.0 can be obtained by students at no charge from the Research Computing Support Center in 244 Wilson Hall. Detailed installation instructions for the standalone Windows version of S-PLUS 8.0 are available online.
S-PLUS standalone version license expires one year after the date of installation. If you are eligible, you may renew this license on an annual basis by installing the new version or if a new license code is available visiting our software registration Web site at web.virginia.edu/rescomp If your S-PLUS is saying it's expired, please feel free to contact us about how to renew it.
Four add-on modules for the statistical software, S-PLUS, are now available. These are:
S-PLUS EnvironmentalStats brings the major environmental statistical methods found in the literature and regulatory guidance documents into one statistical package, along with an extensive hypertext help system that explains what these methods do, how to use these methods, and where to find them in the environmental statistics literature. Also included are numerous built-in data sets from regulatory guidance documents and the environmental statistics literature.
S-PLUS FinMetrics is an econometric analysis tool that offers a modern and flexible platform for financial data analysis. S+FinMetrics incorporates all of the essential analytics, from rolling regression and backtesting functions, to extreme value theory and time series analysis, in a single environment.
S-PLUS SpatialStats is a comprehensive, object-oriented software package for the analysis of spatial data. SPLUS SpatialStats can be used to analyze data arising in areas such as environmental, mining and petroleum engineering, natural resources, geography, epidemiology, demography and others where data is sampled spatially.
S-PLUS Wavelets applies robust wavelet analysis including discrete wavelet transformations, non-decimated wavelet transforms to advanced signal and image, time series, statistical signal and data compression analysis.
