Barplot: Barplot of variable importance

Description

This method can be seen as a visual pendant to toplist. The plot visualizes variable importance by a barplot. The height of the barplots correspond to variable importance. What variable importance exactly means depends on the method chosen when calling GeneSelection, s. genesel.

Arguments

x
An object of class genesel
top
Number of top genes whose variable importance should be displayed. Defaults to 10.
iter
Iteration number (learningset) for which variable importance should be displayed.
...
Further graphical options passed to barplot.
