Usage

gg_scalelocation(fitted.lm, method = "loess", scale.factor = 1, se = FALSE)

Arguments

fitted.lm	a fitted linear model (i.e. lm, glm) that contains fitted regression
method	smoothing method of fitted line on scale-location plot. eg. "lm", "glm", "gam", "loess", "rlm". See https://ggplot2.tidyverse.org/reference/geom_smooth.html for more details.
scale.factor	numeric; scales the point size and linewidth to allow customized viewing. Defaults to 1.
se	logical; determines whether se belt should be plotted on plot

Value

A ggplot object that contains scale-location graph

Examples

library(MASS)
data(Cars93)
cars_lm <- lm(Price ~ Passengers + Length + RPM, data = Cars93)
