[R] interpretation of plot.svm graph

[Indhira, Anusha]

Hi,

I am trying to understand graph generated by plot.svm command. when I use
model.svm <- svm(target.538 ~.,data = svm.data,type = "C-classification")
plot(model.svm,svm.data,T~P,xlab="",ylab = "")
I get attached graph.Can anyone let me know what red,bkack,green circle and cross points represent? Also why are not 1-1 class represented in the graph?

Thanks,
Alily
