Classes and Methods in Package relaimpo

Description

Output objects from package relaimpo have classes relimplm (output from calc.relimp), relimplmboot (output from boot.relimp) and relimplmbooteval (output from booteval.relimp). For classes relimplm and relimplmbooteval, there are methods for plotting and printing, usage of which is described below. For class relimplm, there is in addition a method for extracting slots of the class with $. Since class relimplmbooteval inherits from relimplm, this method can also be applied there.

Usage

## S3 method for class 'relimplm':
print(x,...)

## S3 method for class 'relimplm':
plot(x,...,names.abbrev=4)

## S3 method for class 'relimplmbooteval':
print(x,...)                                    

## S3 method for class 'relimplmbooteval':
plot(x, ..., lev=max(x@level), names.abbrev=4)   

Arguments

x x is an output object from package relaimpo of the required class
... ... further arguments to function plot
names.abbrev names.abbrev is an integer that provides the number of characters to which the bar labels are shortened (default: 4).
lev lev is a numeric that provides the confidence level to be plotted (default: maximum available confidence level).

Details

Print methods produce annotated output for calc.relimp and booteval.relimp. The plot methods produce barplots of relative contributions, either of the metrics alone for output objects of class relimplm from function calc.relimp, or of the metrics with lines indicating confidence intervals for output objects of class relimplmbooteval from function booteval.relimp.

All par() options can be set and should work on plot. Exception: mfrow is set by the plot function, depending on the number of metrics to plot.

In addition, there is a method that allows using $ for extracting slots of classes relimplm and relimplmbooteval, i.e. elements from results of functions calc.relimp and booteval.relimp can be extracted as though the output objects were lists.
