plotD3 {ingredients}R Documentation

Plots Ceteris Paribus Profiles in D3 with r2d3 Package.

Description

Function plotD3.ceteris_paribus_explainer plots Individual Variable Profiles for selected observations. It uses output from ceteris_paribus function. Various parameters help to decide what should be plotted, profiles, aggregated profiles, points or rugs.

Find more details in Ceteris Paribus Chapter.

Usage

plotD3(x, ...)

## S3 method for class 'ceteris_paribus_explainer'
plotD3(
  x,
  ...,
  size = 2,
  alpha = 1,
  color = "#46bac2",
  variable_type = "numerical",
  facet_ncol = 2,
  scale_plot = FALSE,
  variables = NULL,
  chart_title = "Ceteris Paribus Profiles",
  label_margin = 60,
  show_observations = TRUE,
  show_rugs = TRUE
)

Arguments

x

a ceteris paribus explainer produced with function ceteris_paribus()

...

other explainers that shall be plotted together

size

a numeric. Set width of lines

alpha

a numeric between 0 and 1. Opacity of lines

color

a character. Set line color

variable_type

a character. If "numerical" then only numerical variables will be plotted. If "categorical" then only categorical variables will be plotted.

facet_ncol

number of columns for the facet_wrap

scale_plot

a logical. If TRUE, the height of plot scales with window size. By default it's FALSE

variables

if not NULL then only variables will be presented

chart_title

a character. Set custom title

label_margin

a numeric. Set width of label margins in categorical type

show_observations

a logical. Adds observations layer to a plot. By default it's TRUE

show_rugs

a logical. Adds rugs layer to a plot. By default it's TRUE

Value

a r2d3 object.
