[R] kernlab: ksvm() bug?

[Immanuel]

Hello all,

I'm trying to run a gird parameter search for a svm.
Therefore I'M using the  ksvm function from the kernlab package.
----
svp <- ksvm(Ktrain,ytrain,type="nu-svc",nu=C)
----

The problem is that the optimization algorithm does not return
for certain parameters.

I tried to use setTimeLimit() but that doesn't seem to help.
I suspect that ksvm() calls c code that does not respond to the time limit.

I don't know what else to try. Should this be considered to be a bug?
Does anyone know a workaround?

best regards,
Immanuel
