This is quite surprising... Does anybody know anything about it?

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
If you ***look at the code*** for arima you will see that ``%+%'' is
defined
in terms of a call to ``.Call()'' which calls ``R_TSconv''. 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
Just a quick note on your original question:
if you use edit(arima), you have to remember that it returns the
modified function, which then must be stored.
I.e, use
arima-edit(arima)
instead of just
edit(arima)
,and changes should be stored.
THIS IS IT.
IMHO, this should be written in BOLD

Hello,

Dear members of the list,
I'm a beginner in R and I'm having some trouble with: Error in
optim(init[mask], armafn, method = BFGS, hessian = TRUE, control =
optim.control, :
non-finite finite-difference value [8]
when running arima.
I've seen that some people have come accross the same
7 matches
