galtonpeas


In a paper presented to the Royal Institute on February 9, 1877, Sir Francis Galton discussed his experiments on sweet peas in which he compared the sweet peas produced by parent plants to those produced by offspring plants. In these experiments he could observe inheritance from one generation to the next. Galton categorized the parent plants according to the typical diameter of the peas they produced.

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.
