Lattice Functions for Visualizing Resampling Differences

Lattice functions for visualizing resampling result differences between models

Keywords
hplot
Usage
## S3 method for class 'diff.resamples':
densityplot(x, data, metric = x$metric, ...)## S3 method for class 'diff.resamples': bwplot(x, data, metric = x$metric, ...)## S3 method for class 'diff.resamples':
levelplot(x, data = NULL, metric = x$metric[1], what = "pvalues", ...)## S3 method for class 'diff.resamples': dotplot(x, data = NULL, metric = x$metric[1], ...)
Arguments
x
an object generated by diff.resamples
data
Not used
what
levelplot only: display either the "pvalues" or "differences"
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 histogram, densityplot, dotp
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.
