dotplot.diff.resamples: Lattice Functions for Visualizing Resampling Differences

Description

Lattice functions for visualizing resampling result differences between models

Usage

# S3 method for diff.resamples
dotplot(x, data = NULL, metric = x$metric[1], ...)

Arguments

x

an object generated by diff.resamples

data

Not used

metric

a character string for which metrics to plot. Note: dotplot and levelplot require exactly two models whereas the other methods can plot more than two.

…

further arguments to pass to either densityplot, dotplot or levelplot

Value

a lattice object

Details

densityplot and bwplot display univariate visualizations of the resampling distributions. levelplot displays the matrix of pair-wide comparisons. dotplot shows the differences along with their associated confidence intervals.
