This directory contains Lisp-Stat 1.0 Alpha 1, a first attempt at producing a Common Lisp version of Lisp-Stat. This version contains NO graphics, but should implement all the non-graphical facilities of Lisp-Stat. The implementation uses C code from XLISP-STAT for linear algebra and probability distributions, so this code is dependent an a CL's foreign function interface. At this time, three CL's are supported: AKCL (at least verision 1-600) for UNIX systems, Franz' Allegro CL for UNIX systems, and Macintosh CL (version 2.0b1). Separate README files describe each version The object system is the system described in the Lisp-Stat book. Its implementation is in the file lsobjects.lsp in this directory and also included in the tar file. On A DEC 3100 or 5000 the AKCL version of Lisp-Stat runs about half as fast as xlispstat on a standard battery of tests if xlispstat is given an (expand 30) command. I seem to recall that on a sun3 this the AKCL code and xlispstat code run at about the same speed. I have not yet confirmed this. If so, then the relative performance of the AKCL version to xlispstat may be quite hardware-dependent. The Allegro version on a DEC 5000 is considerably slower and larger than the AKCL version, but I have not yet figured out how to tune Allegro's memory management. The Macintosh CL version seems to run at least as fast as xlispstat on the Macintosh. To port this code to another CL, you need to Edit defsys.lsp to add any necessary definitions Add a top level to lstoplevel.lsp (this is only needed if you want to recover the history mechanism, which is broken by shadowing *, etc.) Write versions of the lisp and/or C glue files to interface to the C code in lib. Experiment with tuning the memory management to run reasonably in statistical applications. If you do port this code to another CL, please let me know so I can add it to this distribution.
