lakes


These data give the number of known
crustacean zooplankton species for 69 world lakes.  Also included are a number
of characteristics of each lake.  There are missing values.


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.
