Over the weekend, you should read pages 1-22, 281-291 of "Statistics. An Introduction using R" by Michael J. Crawley.
I also asked you to find in your data a file and try to read it into R.
Lecture 3: Functions and loops.

Lecture 5: More about statistical tests.
notes: [pdf] [TeXmacs]
I asked you to read pages 131-167 from "Statistical Computing". The following zip file contains the data that is used. You'll need to read it into R. data.zip.
Lecture 6: Plots and distributions.

R Documentation:
"simpleR - Using R for Introductory Statistics" by John Verzani
This is a very nice introduction to R. Pages 1-18 cover most of what we'll learn in the first class.
"R for Beginners" by Emmanuel Paradis
This is a good introduction to the internals of R, more from a programmers direction. I will go some into the internals of R, but if you want to learn more about how to multiply matrices, more about how to read files, etc., read this.
"Using R for Data Analysis and Graphics" by J. H. Maindonald
This document mainly talks about doing graphics in R. It has a nice introduction to the windows interface.
How to install xemacs and ess on windows (This document is taken from this site)
Graph gallery- a cool site that contains pictures of graphs produced by R. This can help you make just the right plot!
Function finder - a web page that groups functions in R by what they do.
(Sadly, gone. This one is in the Wayback machine)
R Data Import/Export - explains how to export data from R to files, and to different database formats. The DBI interface on page 14 is what ROracle also uses, so that section explains some of what we learned in class.
The ROracle Package - explains more about interfacing an oracle database from R. It is fairly technical and is a manual of the different functions rather than a tutorial.
