gasdata

This data frame contains the average monthly volume
of natural gas used in the furnace of a 1600 square foot
house located in London, Ontario, for each month from 2006 until 2011. 
It also contains the average temperature 
for each month, and a measure of degree days. Insulation was 
added to the roof on one occasions, the walls were insulated on a second
occasion, 
and the mid-efficiency furnace was replaced with a high-efficiency
furnace on a third occasion.

datasets

Most of this package consists of data sets from the
textbook Introduction
to Linear Regression Analysis, by Montgomery, Peck
and Vining.  All data sets from the 3rd edition are included
and many from the 6th edition are also included.
The package also contains some additional data sets and functions.
