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 (ingo@jhu.edu) and Charles Kooperberg (clk@fredhutch.org)..
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.
