Put the downloaded file VR5.* in an empty directory. Use any of
gzcat VR5.tar.gz | tar xvf - unzip VR5.zip gzcat VR5.gz | sh gzip -dc VR5.gz | sh zcat VR5.Z | sh uncompress -c VR5.Z | shto unpack the software to various information files and the subdirectories MASS, class, nnet, spatial, treefix and test. (Directory test contains tests and instructions to use them.) Now follow the instructions in the file Install in the top-level directory.
If you not have a working nroff, download VR5help.tar.gz and use
gzcat VR5help.tar.gz | tar xf - touch */.Data/.Cat.Help/*
Once installed, the libraries are made available via library commands such as
library(MASS, first=T) library(nnet) library(spatial) library(class) library(treefix, first=T)
Use any of
zcat VR2scripts.Z | sh uncompress -c VR2scripts.Z | sh gzcat VR2scripts.gz | sh gzip -dc VR2scripts.gz | shto unpack the scripts to directory scripts. The file ch08 contains the code from Chapter 8, and so on. These files can be used to cut-and-paste from an editor to the S-Plus session.
Read (and follow) the instructions in the file Install.
