Dear all, In the svm() function in the package e1071, is there anyway to get the signed distance of a sample point to the separating hyperplane in the feature space? Namely, if the separating hyperplane is given by f(x) = h(x)^T * w - rho, is there any way to get f(x)? Also, in the returned values of the function svm(), what does "$coefs" mean? It is said to be the "corresponding coefficients times the training labels", but I don't know what is that "corresponding coefficients" denoting? Thank you very much! Best, Qing
Dear Qing, look at the file "svminternals.txt" in the /doc subdirectory of the installed e1071 package (or inst/doc in the source package), that should help.
