A working introduction to time series analysis in R
From
http://www.statoek.wiso.uni-goettingen.de/veranstaltungen/zeitreihen/sommer03/ts_r_intro.pdf
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
http://www.stats.uwo.ca/faculty/aim/tsar/tsar.pdf
I was able to get the code working on Pages 34, 40
