...saved, * If I copy the code and I save it like a different function, I get the hard error: "Error in Delta %+% c(1, -1) : object "R_TSconv" not found" Anybody can give me a hint? I miss matlab's easy way of doing this ("edit function.m"). Thanks in advance MarC (Acompany) [[alternative HTML version deleted]]

...nux/suse/ Additionally I put binaries for DEC Alpha systems running Digital Unix 4.0 under ftp://ftp.ci.tuwien.ac.at/pub/R/bin/osf/osf4.0/alpha/ These packages are available as rpms and as a setld kit. setld is the Digital Unix package maintanance tool, see setld(1), ask your admin or read the acompanying README files how to use it. Of course, if you want to use the rpms you first have to get "rpm" running on your DU system. It is (normally) available at ftp://ftp.uni-klu.ac.at/pub/uni-klu.ac.at/rpms/RPMS/osf4.0/ But currently this site is under reconstruction, so please check aga...

Hello all, I''m having fun again with the arima function. This time I read in: http://www.stat.pitt.edu/stoffer/tsa2/R_time_series_quick_fix.htm <<It has recently been suggested (by a reliable source) that using xreg in arima() does NOT fit an ARMAX model [insert slap head icon here]. This will be investigated as soon as time permits.>> (by R.H. Shumway & D.S. Stoffer)

So >apparently >R_TSconv is a C or Fortran function or subroutine in a ``shared >object library'' >or dll upon which arima depends. Hence to do anything with it you'll >need to get >that shared

Thanks a lot to everybody that helped me out with this. Conclusions: (1) In order to edit arima in R: >fix(arima) or alternatively: >arima<-edit(arima) (2) This is not contained in the "Introduction to R" manual. (3) A "productive" fix of arima is attached (arma coefficients printed out and error catched so that it doesn't halt parent loops to search for
