Class Notes

Resources for R

You want the "Precompiled binary distribution", not the "source code". For Windows installation, go to the link for "Windows (95 and later)", open folder "base", and click on SetupR.exe to download the installer SetupR.exe. Then run SetupR.exe to install R on your computer.

Because you are running R in Windows, not UNIX, you should skip the Introduction, which is mostly about UNIX, and begin with Entering Data.


These exercises are for self-directed learning. They will not be graded and you do not have to hand them in. However, you will find that writing down your interpretation of the results is an excellent way to clarify your understanding. If you complete your report and submit it to me, I will read it and return it with comments and suggestions.

Learn about these famous statisticians!
Florence Nightingale, William Sealey Gosset, Sir Ronald Aylmer Fisher and John Wilder Tukey.
George Waddel Snedecor named the F-distribution in honour of Fisher.
Gosset and I both studied at New College, Oxford, but we were not there at the same time.
John Tukey died July 26, 2000. He is credited with many statistical innovations, including the boxplot and the stem-and-leaf plot, and for coining new words such as "bit" (a contraction of "binary integer") and "software".

What can you find out about Poisson? His name? His dates? The Prussian horse kick data?
