In latrend: A Framework for Clustering Longitudinal Data

Quantile-quantile plot

Description

Plot the quantile-quantile (Q-Q) plot for the fitted lcModel object. This function is based on the qqplotr package.

Usage

## S4 method for signature 'lcModel'
qqPlot(object, byCluster = FALSE, ...)

Arguments

object	The lcModel object.
byCluster	Whether to plot the Q-Q line per cluster
...	Additional arguments passed to qqplotr::geom_qq_band(), qqplotr::stat_qq_line(), and qqplotr::stat_qq_point().

Value

A ggplot object.
