Abstract:

Lisp-Stat is a statistical computing environment based on the Lisp language. In addition to standard numerical methods, Lisp-Stat includes a dynamic graphics system for use on bitmapped graphics displays. Dynamic plots provided include histograms, scatter plots, rotatable plots, and scatter plot matrices. The graphics system is designed to be extensible using the Lisp language and an object-oriented programming system. This paper provides a brief introduction to the Lisp-Stat system and reviews some recent additions, including byte code compilation and interfacing to foreign code. Plans for future developments, including a new virtual machine, multi-threading support and possible revisions to the graphics system are outlined as well.
