Hi :    

      I have several puzzling questions about R package "e1071" , svm( ) function:    

  1. what is the model output about "model$coefs", is it (alfa(i)*y(i) )???? and "model$rho" ? is it "- b"????
  2. if I want to know w , is it model$SV * model$coefs ?
  3. if I just want to use kernel="linear", how the output" C" and "gamma " come out? for example:
