Hi, all, 

I am testing the xval() function under MLInterfaces package following
the documentation.  

> lk1 <- xval(smallG, "ALL.AML", knnB, xvalMethod="LOO",

I am wondering when I invoke above, is knnB being invoked with the
default set of parameters to do Leave-One-Out cross validation? If so,
is it possible to specify my own parameters, such as k and l?

Thanks in advance.
