Note: All of this code requires the nlme library

Code that has been discussed in class or lab includes:

• spruce.r Code to fit a 2-sample t-test and a nested variance components model to the spruce data.
• topsin.r Code to fit a split-plot ANOVA to the topsin data
• chute2.r Code to fit random coefficient regression models to the parachute line breaking strength data. Includes quite a few comments to explain the various bits of code.
