Object returned from a call to GeneSelection

rankings:: A list of matrices. For the two-class case and the multi-class case where a genuine multi-class method has been used for variable selection, the length of the list is one. Otherwise, it is named according to the different binary scenarios (e.g. 1 vs 3). Each list element is a matrix with rows corresponding to iterations (different learningsets) and columns to variables. Each row thus contains an index vector representing the order of the variables with respect to their variable importance (s. slot importance)
importance:: A list of matrices, with the same structure as described for the slot rankings. Each row of these matrices are ordered according to rankings and contain the variable importance measure (absolute value of test statistic or regression coefficient).
method:: Name of the method used for variable selection, s. GeneSelection.
scheme:: The scheme used in the case of a non-binary response, one of "pairwise", "one-vs-all" or "multiclass"

show: Use show(genesel-object) for brief information
toplist: Use toplist(genesel-object, k=10, iter = 1) to display the top first 10 variables and their variable importance for the first iteration (first learningset), s.toplist.
plot: Use plot(genesel-object, k=10, iter=1) to display a barplot of the variable importance of the top first 10 variables, s. plot,genesel-method
