There are some obvious errors in this edition, and I am not sure if it is the legal copy.....
For example, in the page 98, it should talk about time series using tslm ( ) function but the book shows lm()... and some formats of words are not fine. It is too weird...
It costs my 8 corns but got a wrong one.... hope someone can check the contents more seriously before releasing it, do not to lead others' study in a wrong way.

There could be better functions/packages handling time series analysis, but I am sure in this case, lm() works just fine as well.
