ksvm method.
My (normalized) kernel matrix is of size 1309*1309, my results vector
has the same length.
I am using C-svc.
My kernlab call is something similiar to this:

debugging S4 methods
Hi all,
Does anyone know how to debug S4 methods? In my case I want to find an
error in the specc-function of the kernlab-package.
As this seems to be a S4-method the normal S3 debugging can't be
applied apparently (e.g. debug(s3function.someclass)).
So in my case
> debug(specc:kernlab)
seems only to debug the generic-function:
> specc:kernlab

I am using caret with kernlab/ksvm. I will simplify my problem to a basic data set which produces the same problem. I have read the caret vignettes as well as documentation for ?train. I appreciate any direction you can give. I
