This program is one that an instructor could use to introduce simple linear regression. This R module uses a simple simulated data set and allows a sequence of graphs which show what regression is trying to do, how you can use it for prediction, and shows the residual plot. The last part uses a quadratic data set to show what the residual plot looks like in this case.
You can replace the default x and y by changing the underlying R code - for example: x=1:20 and y=1:20+rgamma(20,2,1)
