Hello everybody,

I'm using the kernlab package, but I'm yet to find how to map existing
variables onto a kha representation.

here is an example:

> names(dttest)
[1] "rapCADuree"         "CA"                 "DifferenceCommande"
> kha(~.,data=dttest[1:1000,],features=4,na.action=na.exclude)->khatest
> eig(khatest)
    Comp.1     Comp.2     Comp.3     Comp.4
1647.91346   20.08602   82.15760   15.09415
> plot(predict(khatest,dttest[1:1000,]),col=model[1:1000])

Then, as it looks like a PCA, I would like to draw arrows of source
variables onto the new representation, but I can't find how I could
proceede.

Any ideas ?

Many thanks & best regards,

Laurent
