1. Download S-PLUS
Students:
You must have a copy of S-PLUS for Windows, version 6.1 or higher. If
you are a university student, you can download a free copy of
the S-PLUS Student Edition to install on your personal Windows
PC. Visit http://elms03.e-academy.com/splus/, follow the
instructions to register as a student, and download the software.
Install S-PLUS on your computer. We recommend allowing the
installation program to choose file locations.
Instructors:
You must have a copy of S-PLUS for Windows, version 6.1 or higher.
(You can also use a Unix/Linux version, but it lacks the menu interface
that we feel is important for student use.) You can obtain a trial
version and contact information for personal or site licenses at http://www.insightful.com/industry/academic/.
2. Download two new libraries for S-PLUS:
The IPSdata library
http://www.insightful.com/Hesterberg/bootstrap/
and the
S+Resample library
http://www.insightful.com/downloads/libraries
The libraries are sent as ZIP archives. You will require a program that
enables you to open these files, such as WinZip.
Save the archives in a convenient location, then unzip both. Not all
zip programs behave the same, alas. We recommend right-clicking on each
archive, choosing "Extract to...." and specifying "IPSdata" as the
destination folder.
Then look at the .Prefs folders in both the IPSdata and
resample folders: right-click, choose "Properties," and be sure
that "Read-only" is checked. It is set that way, but some zip programs
lose this setting. If not checked, then select it and choose the
option to apply read-only to all files in the folder.
2. Place the IPSdata and resample folders in your S-PLUS
library directory. If you allowed the S-PLUS installer to choose
folder locations, this directory is at C:\Program
Files\Insightful\splusXX\library where XX is the version number of
your software, such as splus62.
3. Try it out:
You are now ready to add new resampling features to S-PLUS and to load
the IPS data sets. Launch S-PLUS by clicking its icon. In the "File"
menu at the far left, go to "Load Library". The IPSdata library
should be the first entry in the list of libraries you see in the
dialog box that appears. Be sure its name is highlighted, then click
OK. This loads all of the IPS data files and also loads the S+Resample
library.
To check that S-PLUS is ready to use for resampling, look at the
"Statistics" menu. Go down to "Resample". You should see entries for
"Bootstrap" and "Permutation Test". Then, in the S-PLUS Object
Explorer, click on "Search Path" if it is not already expanded.
(You can open the Object Explorer by clicking on an icon that looks
like an open box with three things floating above it.) Click on
"IPSdata". You should now see a list of all the data sets for IPS.
Finally, there should also be a new entry at the right of the main
S-PLUS menu bar, titled IPSdata. This menu has options to view
the manual, view help files, view example code for exercises, or open a
dataset.
