Dear all, I am using the package e1071 for modeling SVM. I obtain a model from the data and I can plot the results; the plot shows the support vectors (as 'X's) and the shaded areas as it should be. However, I don't like the plot generated from the model and I would like instead to have more control upon the plotting; in particular, I would like to draw the hyperplane on plots I have already made from the data available. Is there a way to extract the values that are used to draw the hyperplane? That is: plot(model) -- where model is obtained from svm() -- draws an area in blue and one in red based on some values provided by model; can I get these values so I can plot a line in a pre-existing plot? Also, it is possible to extract the positions of the support vectors? The names of the model generated by svm() are: > names(mod) [1] "call" "type" "kernel" "cost" [5] "degree" "gamma" "coef0" "nu" [9] "epsilon" "sparse" "scaled" "x.scale" [13] "y.scale" "nclasses" "levels" "tot.nSV" [17] "nSV" "labels" "SV" "index" [21] "rho" "compprob" "probA" "probB" [25] "sigma" "coefs" "na.action" "fitted" [29] "decision.values" "terms"
Which one should I look at?
