[BioC] optimizing class weights in e1071

Dear list,
Is there a way to optimize class weights together with the rest of 
hyperparameters for SVMs in tune function (e1071)? That is, I don't know 
if tune function besides the optimization of the hyperparameters can 
optimize a range of values of class weights at the same time (a priori, 
the best class weights are also unkown).
