ya, unfortunately k was actually a dataframe and not a matrix when it was

Thanks Ista!
Indeed this is the workaround I had found, but not very practical as it
fails on univariate series, so you should know before which class is the
object... I feel a head.mts would make sense, or did I misunderstand

Another way that I like is reshape::melt.list() because it keeps track
of the name of the original data.frames,
l = replicate(1e4, data.frame(x=rnorm(100),y=rnorm(100)), simplify=FALSE)
system.time(a - rbind.fill(l))

How do you evaluate the predictive models? For example if I have:

Hi,
basically, you know 5 periods later. If you use a good error measure,
that is.
I am a big believer in AIC for model selection. I believe that arima()
also gives you the AIC of a fitted model, or try AIC(arima1).
Other ideas include keeping a holdout sample or some such.
