Update the options of a modelStudio object

This function updates the options of a modelStudio object. WARNING: Editing default options may cause unintended behavior.

ms_update_options(object, ...)

Arguments

object

A modelStudio created with modelStudio().

...

Options to change in the form option_name = value, e.g. time = 0, facet_dim = c(1,2).

Value

An object of the r2d3, htmlwidget, modelStudio class.

Options

Main options:

scale_plot

TRUE Makes every plot the same height, ignores bar_width.

show_boxplot

TRUE Display boxplots in Feature Importance and Shapley Values plots.

show_subtitle

TRUE Should the subtitle be displayed?

subtitle

label parameter from explainer.

ms_title

Title of the dashboard.

ms_subtitle

Subtitle of the dashboard (makes space between the title and line).

ms_margin_*

Dashboard margins. Change margin_top for more ms_subtitle space.

margin_*

Plot margins. Change margin_left for longer/shorter axis labels.

w

420 in px. Inner plot width.

h

280 in px. Inner plot height.

bar_width

16 in px. Default width of bars for all plots, ignored when scale_plot = TRUE.

line_size

2 in px. Default width of lines for all plots.

point_size

3 in px. Default point radius for all plots.

[bar,line,point]_color

[#46bac2,#46bac2,#371ea3]

positive_color

#8bdcbe for Break Down and Shapley Values bars.

negative_color

#f05a71 for Break Down and Shapley Values bars.

default_color

#371ea3 for Break Down bar and highlighted line.

Plot-specific options:

** is a two letter code unique to each plot, might be one of [bd,sv,cp,fi,pd,ad,rv,fd,tv,at].

**_title

Plot-specific title. Default varies.

**_subtitle

Plot-specific subtitle. Default is subtitle.

**_axis_title

Plot-specific axis title. Default varies.

**_bar_width

Plot-specific width of bars. Default is bar_width, ignored when scale_plot = TRUE.

**_line_size

Plot-specific width of lines. Default is line_size.

**_point_size
