Some notes :

On page 13 for :summary(lm(lbeer t+t2+sin.t+cos.t))

Ensure you have summary(lm(lbeer ~ t+t2+sin.t+cos.t)) to work

As of page 19, I am not sure where to retreieve LakeHuron data. Is it part part of the timeSeries package folder?  I could not find it

There also appears to be a more advanced PDF at

I was able to get the code working on Pages 34, 40
