blkbox (version 1.0)

ncv.plot: Nested Crossfold Validation Performance Plot.

Description

Compares the performance of each algorithm in a boxplot. Each holdout will contribute at least one data point to each algorithms boxplot.

Usage

ncv.plot(obj, metric, y_ranges, title)

Arguments

obj

An object produced by the blkboxCV function.

metric

Which metric you wish to plot, can only plot those specified to the blkboxNCV function at time of running. Area under the Receiver operating curve = "AUROC", Accuracy = "ACC", Error rate = "ERR", Matthews correlation coefficient = "MCC", F-1 score = "F-1". Default is the first metric specified to your NCV arguments vector.

y_ranges

is the y axis limits for the plot, defaults to c(0,1). Must be a numeric vector with two entries.

title

the title to be adhered to the plot. Default is no title.

Examples

ncv.plot(blkboxNCV(...), metric = "AUROC", title = "NCV Performance Boxplot")
