If you install then svmpath library ! run the attach source file.

In the R-help of the svm function of the package e1071 it's explained that
this function also makes estimation of density.
But when i made for example
I just have a binary classification of X like SVM do whereas i want an
estimation of the density which generates our sample X ...
I don't know if it's possible and if someone has already use this function
to do that.
