[R] help on ar(1)

[ONKELINX, Thierry]

Have a look at the gls() function from the nlme package. The helpfile of gls() contains an example of an AR1 structure.

HTH,

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
