Using lag
Dear all,
I am having difficulties using the seemingly-simple function lag.
I have a dataframe with several weather variables (maxitemp,
windspeed, rainfall etc), and the response variable (admissions). The
dataset is fairly large (1530 observations). I simply want to model the
response against a lag of a couple of the explanatory variables, say
maxitemp and rainfall. I would like to look at

After an RSiteSeach("Box.test") I found some discussion regarding the degrees
of freedom in the computation of the Ljung-Box test using Box.test(), but did
not find any posting about the proper degrees of freedom.
Box.test() uses "lag=number" as the degrees of freedom. However, I believe
the correct degrees of freedom should be "number-p-q" where p and q are
