Windspeed data collected at a test site for a windmill, and also at four nearby long-term weather
site, in Northern South Dakota.  
Data collected every six hours for all of 2002, except that all of the month
of May and a few other observations are missing.

This package is a companion to the textbook S. Weisberg (2005),
"Applied Linear Regression," 3rd edition, Wiley. It includes all the
data sets discussed in the book (except one), and a few functions that
are tailored to the methods discussed in the book.  As of version 2.0.0,
this package depends on the car package. Many functions formerly
in alr3 have been renamed and now reside in car.
Data files have beeen lightly modified to make some data columns row labels.
