Thanks.
One more question. When I do summary to see the coefficients how can i tell
R to print just some of the coefficients?
Thanks again

The summary currently doesn't provide this feature. But you can use something
like coeftest(obj)[1:3,] or coeftest(obj)[myreg,] or something like that...

Hi everyone!
I am making some time series models, and as i want to compare a lot of

from the models. My question is, how can I extract the BIC and AICc from the
model?
As an example:

Dear R users,
Suppose I want to randomly generate some data, in matrix form, randomly
swap some of the elements and calculate trace of the matrix for each of
these stages. If the value of trace obtained in the later is bigger than
the former, drop the latter matrix and go back to the former
