[R] weighted nonlinear least squares wtih gnls

[Peter Schlattmann]

Dear all,

I try to perform weighted linear least squares wtih using glns.

The weights are something like

ww<-rep(c((0.1,0.9),n))

my dataframe is named test and I add ww to test by test$ww

Now using 

vf1<-varFixed(~ww)
vf1<-Initialize(test,vf1)

does not produce any usable weights. Does anyone have a
working exampel for this kind of problem?

Thans a lot for oyur help
Peter
