What does this error mean while running the ksvm of kernlab package in R

Question

I am calling the ksvm method of the kernlab package in R using the following syntax

svmFit = ksvm(x=solTrainXtrans, y=solTrainYSVM, kernel="stringdot", kpar="automatic", C=1, epsilon=0.1)

The x parameter is a data.frame with feature values and the y parameter is a list with various values.

I get the following error while run the above line.

Error in do.call(kernel, kpar) : second argument must be a list

What is it trying to tell me here?

`kpar="automatic"` is not implemented for this kernel. The parameter expects a list. — Roland, Oct 26 '14 at 14:04

Try setting kpar = list(length = 4, lambda = 0.5)
Does it help?
