[R] X-12-ARIMA

[Paul Gilbert]

(subject changed from "[R] a doubt" )

The fortran source code for X-12-ARIMA seems to be available at 
<http://www.census.gov/srd/www/x12a/x12down_unix.html>. Incorporating 
this into a standard R package would be a much better approach than 
trying to hack an OS specific version with system calls to a .exe file. 
I expect there will be a fair amount of work in either case, and I don't 
have time to look at it now. If anyone wants to do the real work then I 
would be interested in using it (but using calls to a .exe would not be 
very useful to me). The first thing to check would be the license, as I 
have not looked at it. The next is probably the question of whether the 
fortran is nicely organized in subroutines without IO, so R can call 
those and avoid fortran IO problems.

(Perhaps there are R users at the U.S. Census Bureau that would be 
willing to help?)

Specifically, I'm trying to create an interface in R for the X-12-ARIMA and TRAMO SEATS, for the versions that run in MS-DOS. This problem awake in me the interest for make interfaces to comparing some Bayesian models for classification that where implemented in MS-DOS to. The question for you is if you know about the existence of an R function that allows me to run -in Windows- executable files in MS-DOS from the R command window.
