Hi, all
I can not figure this out, please have a look and help me out.
thank you!
Note: this is in SPLUS, not R.
Note 1: This mailing list is about R, not S-PLUS.
Note 2: Your code is not reproducible - we don't have the data.
I'd suggest that you repost your question including an easily reproducible example on the S-News mailing list.

I have following code *********************************** modfit<-function(yir,yew, ft) {
n<-length(yew) yew<-yew[1:(n-1)]
yy<-yir-ft xx<-yew-ft
n<-length(xx) xx0<-xx[2:n] yy0 <-yy [2:n]
xx1<-xx[1:(n-1)]
fit <- garch(yy0~xx0 + xx1+var.in.mean, ~garch(1,1),cond.dist='ged') summary(fit) }
fs1hca<-modfit(s1hca.r, s1hca.ew, zfr)
**************error message is ***************
Problem in garch(yy0 ~ xx0 + xx1 + var.in.mean, ~ ..: Object "xx0" not found Use traceback() to see the call stack
It is really weird, I tried step by step, the code works, but what's the problem with xx0,I can't figure it out.
thank you for any suggestion.
best regards yong
