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.
