toplist: Display 'top' variables

In CMA: Synthesis of microarray-based classification

Description

This is a convenient method to get quick access to the most important variables, based on the result of call to GeneSelection.

Usage

toplist(object, k = 10, iter = 1, show = TRUE, ...)

Arguments

object	An object of genesel.
k	Number of top genes for which information should be displayed. Defaults to 10.
iter	teration number (learningset) for which tuning results should be displayed.
show	Should the results be printed ? Default is TRUE.
...	Currently unused argument.

Value

The type of output depends on the gene selection scheme. For the multiclass case, if gene selection has been run with the "pairwise" or "one-vs-all" scheme, then the output will be a list of data.frames, each containing the gene indices plus variable importance for the top k genes. The list elements are named according to the binary scenarios (e.g., 1 vs. 3). Otherwise, a single data.frame is returned.
