Lattice Functions for Visualizing Resampling Differences
Lattice functions for visualizing resampling result differences between models
## S3 method for class 'diff.resamples' dotplot(x, data = NULL, metric = x$metric[1], ...)
x |
an object generated by |

metric |
a character string for which metrics to plot. Note:

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.
