phiPlot: Plot of phi versus y and boxplot of y

In nunompmoniz/IRon: Solving Imbalanced Regression Tasks

Plot of phi versus y and boxplot of y

Description

The phiPlot function uses a dataset ds containing many y values to produce a line plot of phi versus y and a boxplot of y, and aligns them, one above the other. The first extreme value on either side of the boxplot should correspond to the point where phi becomes exactly 1 on the line plot. This function is dependent on the robustbase, ggplot2 and ggpubr packages, and will not work without them.

Usage

phiPlot(ds, phi.parms = NULL, limits = NULL, xlab = "y", ...)

Arguments

ds	Dataset of y values
phi.parms	The relevance function providing the data points where the pairs of values-relevance are known. Default is NULL
limits	Vector with values to draw limits. Default is NULL
xlab	Label of the x axis. Default is y
...	Extra parameters when deriving the relevance function

Value

A line plot of phi versus y, as well as a boxplot of y

Examples

ds <- rnorm(1000, 30, 10); phi.parms <- phi.control(ds); phiPlot(ds,phi.parms)
ds <- rpois(100,3); phiPlot(ds)
