textplot_influence: Influence plot for text scaling models

Description

Plot the results of a fitted scaling model, from (e.g.) a predicted textmodel_affinity model.

Usage

textplot_influence(x, n = 30, ...)

Value

Creates a base R plot of feature influences of the median influence by the log10 median rate of the feature, and invisibly returns the elements from the call to plot().

Arguments

x

the object output from influence() run on the fitted or predicted scaling model object to be plotted

n

the number of features whose influence will be plotted

...

additional arguments passed to plot()
