R Documentation

Caterpillar plot

Description

Caterpillar plots for random effects models using ggplot.

Usage

ggcaterpillar(re, qq = TRUE, likeDotplot = TRUE)

Arguments

`re`	random effects from lmer object
`qq`	if `TRUE`, returns normal q/q plot; else returns caterpillar dotplot
`likeDotplot`	if `TRUE`, uses different scales for random effects, i.e., `facet_wrap`

Details

Behaves like qqmath and dotplot from the lattice package; also handles models with multiple correlated random effects

Examples


library('lme4')
fit <- lmer(Reaction ~ Days + (Days | Subject), data = sleepstudy)

ggcaterpillar(ranef(fit, condVar = TRUE))

## compare (requires lattice package)
lattice::qqmath(ranef(fit, condVar = TRUE))
