CrossValidationResult Accessors

1 2	## S4 method for signature 'CrossValidationResult' folds(object)

object

a cross validation result object (can be extracted from KeBABS model with accessor cvResult)

folds: returns the folds used in CV
performance: returns a list with the performance values

: folds: return the CV folds.
: performance: return the collected performance parameters.

## create kernel object for normalized spectrum kernel
specK5 <- spectrumKernel(k=5)
## Not run: 
## load data
data(TFBS)

## perform training - feature weights are computed by default
model <- kbsvm(enhancerFB, yFB, specK5, pkg="LiblineaR",
               svm="C-svc", cross=10, cost=15, perfParameters="ALL")

## show model selection result
cvResult(model)

## extract fold AUC
performance(cvResult(model))$foldAUC

## End(Not run)
