\title{ 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).
