plotErrorsFoldTwoLayerCV Method to plot the error rate of a two-layer Cross-validation

Description

This method creates a plot that reprenset the error rate in each fold of each repeat of the second layer of cross-validation of the two-layer cross-validation of the assessment at stake. The plot represents the error rate versus the size of gene subsets (for SVM-RFE) or the threshold values (for NSC).

Methods

object = "assessment"

The method is only applicable on objects of class assessment.
