[R] how add objects to an svm graphic

[ale.ambrosi@unipd.it]

Dear all,

I'm not able to solve easily the following simple problem. 
I really hope someone can give me some hints.

I trained an svm (e1071). Now I'd like to show the results graphically.
I used plot.svm and I'd like to add some other objects to the plot:
points, (coloured) ellipses to indicate some intersting regions, curves, 
and so on...
I tried to pass these as additional graphics parameters to pass to 
filled.contour, as indicated in ?plot.svm and in examples in
filled.contour help.

But it doesn't seem to work.

Where is my foult? Can anyone help me? 

Best,
Alessandro


PS: I use R 1.9.0 on a WinXP OS
