This page provides information on how ton install Logic Regression under S-Plus for Linux/Unix. We have no experience in installing Logic Regression under S-Plus for Windows. Note that we do not update the S-Plus version each time we update the R version. Thus, if you are familiar with R we suggest using that instead.
The version for R is available from CRAN. Follow the packages link, and then look for LogicReg.
The instructions below are available as text files for Splus . The current version of the code is recorded in the changelog . Please report bugs to Ingo Ruczinski and Charles Kooperberg .

Download and install Logic Regression under Splus for Linux/Unix

Download the package slogic.tar.gz.

Move the file slogic.tar.gz to a place where you want the library to be

             mv slogic.tar.gz  somewhere/mydirectory/

Execute the following commands:

             cd somewhere/mydirectory/
             gunzip slogic.tar.gz
             tar -xvf slogic.tar
             cd LogicReg
             Splus CHAPTER
             make

Replace Splus by whatever your command is to invoke S-Plus.

Problems are likely related to not having set the environment variable SHOME properly. Some systems managers set up the system so that SHOME is only temporarily set during the S-Plus session. Check this by typing

             printenv SHOME

The reply should be something like

             /usr/local/Splus60

If there is no reply, ask your systems manager what SHOME is, and set it manually before the CHAPTER command and make command.

             setenv SHOME /where/your/shome/is

Your installation is now complete. In S-Plus access the logic regression package by executing

             attach("somewhere/mydirectory/LogicReg")

The function logreg() is the first function that you want to look at.
