Programming

ViSta is written in Lisp, using the XLispStat extensions for statistical software development. The system is completely open and extensible. The Lisp programmer can add whatever capabilities are desired.

What is XLisp-Stat? XLisp-Stat is an object-oriented environment for statistical computing and dynamic graphics that is open, extensible and freely available. XLisp-Stat is meant for high-level statistical programming and data analysis by sophisticated statistical data analysts. XLisp-Stat is based on XLisp, a freely available version of Common Lisp, a functional object-oriented computing language. ViSta is written in XLisp, using the XLisp-Stat system. ViSta is also an open and extensible system which provides all of the power of XLisp and XLisp-Stat for the programmer who wishes to extend ViSta's capabilities. C++, FORTRAN Routines written in C++ and FORTRAN can all be linked with ViSta.
