R help - Dec 2010 - SVM Posterior Probabilities

I am using SVM in R via package e1071 package.  Is it possible to obtain
probabilities of the classification for the test set based on distances from the
classification planes?  This seems possible in Linear Discriminant Analysis (via
lda function in MASS package) through the posterior probabilities field in the
prediction.  However, I am unable to find anything similar for SVM.
Thank you all for your help.Vijay
