R help - Nov 2012 - how are the values in ksvm related to the svm formula ( the parameter for kernal function)

Hi All,

The svm formula, saying the simplest linear one: w*x+b=y.
Where w is the normal vectors of the hyper plane and can be calculated by
sum(alpha(i)*y(i)*x)

The values of ksvm of kernlab has alpha, coef, ymatrix, xmatrix and b. b is sure
the offset. How are the others related ? alpha = alpha, ymatrix= y, and xmatrix
= x? what is coef ?

Thanks a lot!

Regards,
Yan
