plot.mlm_variance_decomp: Plot the variance decomposition of simple slopes

In mlmoderator: Probing, Plotting, and Interpreting Multilevel Interaction Effects

Plot the variance decomposition of simple slopes

Description

Shows the simple slope at each moderator value as a point with two interval layers: an inner confidence interval (fixed-effect uncertainty only) and an outer prediction interval (fixed + random-slope variance). The gap between the two intervals is the contribution of random-slope heterogeneity.

Usage

## S3 method for class 'mlm_variance_decomp'
plot(x, x_label = NULL, y_label = NULL, ...)

Arguments

x	An mlm_variance_decomp object.
x_label	x-axis label. Defaults to moderator name.
y_label	y-axis label. Defaults to "Simple slope of pred".
...	Ignored.

Value

A ggplot object.
