Hi all,

I am using the "svm" command in the e1071 package.

Does it have an automatic way of setting the "cost" parameter?

I changed a few values for the "cost" parameter but I hope there is a
systematic way of obtaining the best "cost" value.

I noticed that there is a "cross" (Cross validation) parameter in the "svm"
function.

But I did not see how it can be used to optimize the "cost" parameter.

By the way, what does a 0 training error and a high testing error mean?
Varying "cross=5", or "cross=10", etc. does not change the training error
and testing error at all. How to improve?

Thanks a lot!

M.
