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. For instance, tsdiag(ar(lh)) tsdiag(arima(lh, order = c(3,0,0))) Thanks...

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)))
