lakemary


78 bluegills were captured from Lake Mary, Minnesota.  On each fish, a
key scale was removed.  The age of a fish is determined by counting the
number of annular rings on the scale.  The goal is to relate length at
capture to the radius of the scale.  


datasets

This package is a companion to the textbook S. Weisberg (2014),
"Applied Linear Regression," 4rd edition, Wiley. It includes all the
data sets discussed in the book and one function to access the textbook's
website.
This package depends on the car package.  Many data files in this package
are included in the alr3 package as well, so only one of them should be
loaded.
