I am trying to replicate ARIMA models in R from SAS. Specifically -
Factored ARMA models, which I can do very easily in SAS (
http://v8doc.sas.com/sashtml/ets/chap7/sect11.htm).
I would like to know if there is a way to do this in any of the R packages.
Thanks in advance,

Hi,
I guess this is pretty basic.
I have 25 variables in the data file (name: score), i.e. X1,X2,.,X25.
I dont want to use score$X1, score$X2 everytime I use these variables.
Is there a way I can rename all these variables as simply X1,X2,.X25

You are close--think names, not titles, as in rownames or colnames (no
reason to completely spell out column). Summary already gave you the
column names, so type ?rownames to learn more.
