pg 99 - set.seed() for the simulation would be helpful

[hachiko1024]

While going through the book, I'm practicing the rcode but the rnorm simulation on pg 99 doesn't have a seed so it's harder to reporduce

set.seed is included in the code and the page mentions "Code for this example is in the folder Simplest." The code in the book is often slightly simplified, but you can find the complete code in the book web page
