HI! I have 2D feature vectors and 2 classes. I want to solve this classification problem with SVM. I create an object XOR of the mlbench library. Then I replace the values of the XOR object with my values. Then I do a plot and I have my data plotted and coloured with the labels from the XOR object. So I replace the class labels in the xor object with my class labels. But when I do a plot with the new class labels every object is coloured in one colour. But half of the points should be in different colour(because different class label). As well when I apply svm on the xor object with th replaced data it finds just one class. someone any idea thx

It is not the purpose of the r-help mailing list that undergraduate students ask questions about their classwork. We have a lab session scheduled for next Wednesday where you can ask questions like this in person. My apologies to the list for the noise that has been generated.
