Is there a way to have the ar function work with tsdiag for on-the-fly visualization of ar fits? I have to fit a great many models of varying order and would like to save the diagnostic graphs.
First you have to produce them, surely?
For instance, tsdiag(ar(lh))
That gives an error. All you have to do is to write an "ar" method for tsdiag -- a good exercise in R programming for you.
tsdiag(arima(lh, order = c(3,0,0)))
