[R] Generating data from an ANOVA model

[Murray Jorgensen]

In my teaching I like to try to get across the meaning of the linear models
assumed in ANOVA by generating artificial data from these models.

When using Minitab I would set up columns of indicator variables for the
factors and any interactions included and add random normal error to a
column of means formed as a linear combination of the indicator columns.

I now want to do something similar in R. I am not looking for the shortest
possible code to do this, but a solution that will make it as obvious as
possible to the students exactly what is going on.
