plot.gg_partialpro: Plot a 'gg_partialpro' object

In ggRandomForests: Visually Exploring Random Forests

Plot a gg_partialpro object

Description

Produces ggplot2 partial dependence curves from the named list returned by gg_partialpro, which wraps varpro::partialpro output.

Usage

## S3 method for class 'gg_partialpro'
plot(x, type = c("parametric", "nonparametric", "causal"), ...)

Arguments

x	A gg_partialpro object.
type	Character vector; one or more of "parametric", "nonparametric", "causal". Defaults to all three.
...	Not currently used.

Details

Each variable produces up to three effect curves: parametric, nonparametric, and causal. The type argument controls which are shown.

Value

A single ggplot or a named list with continuous and categorical elements when both types of predictors are present.

Examples

## ggRandomForests does not depend on the varpro package; we construct a
## minimal mock of the partialpro() output so the example runs everywhere.
