Hello all,

I thought I found it, it is in the arima.R if I use arima to fit the model.

But how could we see the source code of some function in R?

Thanks,

Rebecca

Hello,

I try to look at the source code of predict() it turns out that I cannot find it.

I can see it with debug(library), but not efficient.

Can someone help?

Thanks,

Rebecca

getS3method("predict", "arima")
Pardon -- it's either "Arima" or "arima0" but not "arima" in this case.

But, in general, getS3method is what you're looking for.

The information in the article by Uwe Ligges in this issue of R News:

http://cran.r-project.org/doc/Rnews/Rnews_2006-4.pdf

is still valid.

P.S.  I got that link from the R help system.  Start HTML help, look at 
the "Technical Papers" link, and you'll find all sorts of good stuff.
Thanks,

Rebecca

Hello MW,

Thanks very much!

I use
getS3method("predict","arima0")
And be able to see the source code. 

Have a great day!

Cheers,

Rebecca

Hello,

In the case of predict.Arima, you can type at an R prompt the following.

stats:::predict.Arima

Hope this helps,
