plotD3_aggregated_profiles: Plots Aggregated Ceteris Paribus Profiles in D3 with r2d3...

plotD3.aggregated_profiles_explainerR Documentation

Plots Aggregated Ceteris Paribus Profiles in D3 with r2d3 Package.

Description

Function plotD3.aggregated_profiles_explainer plots an aggregate of ceteris paribus profiles. It works in a similar way to plotD3.ceteris_paribus_explainer but, instead of individual profiles, show average profiles for each variable listed in the variables vector.

Find more details in Ceteris Paribus Chapter.

Usage

## S3 method for class 'aggregated_profiles_explainer'
plotD3(
  x,
  ...,
  size = 2,
  alpha = 1,
  color = "#46bac2",
  facet_ncol = 2,
  scale_plot = FALSE,
  variables = NULL,
  chart_title = "Aggregated Profiles",
  label_margin = 60
)

Arguments

x

a aggregated profiles explainer produced with function aggregate_profiles()

...

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/bar color

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

Value

a r2d3 object.
