lambda_plot {ggDoE}

Lambda Plot: Trace of t-statistics

Description

Lambda Plot: Trace of t-statistics

Usage

lambda_plot(
  model,
  lambda = seq(-2, 2, by = 0.1),
  color_palette = "viridis",
  alpha = 1,
  direction = 1,
  showplot = TRUE
)

Arguments

model

Model of class "lm" or "glm"

lambda

sequence of lambda values to consider for plot. Default is seq(-2,2,0.1)

color_palette

A character string indicating the color map option to use. Eight options are available: "viridis","cividis","magma","inferno","plasma","rocket","mako","turbo". Default is 'viridis'

alpha

The alpha transparency, a number in [0,1]

direction

Sets the order of colors in the scale. If 1, the default, colors are ordered from darkest to lightest. If -1, the order of colors is reversed

showplot

logical indicating to show the main effect plots. If false, a list of tibbles is returned used to obtain the main effects for each factor. Default is TRUE

Value

Lambda plot for tracing t-staitics across different values of lambda (in ggplot2)

Examples

mod <- lm(s2 ~ (A+B+C)^2,data=original_epitaxial)
lambda_plot(mod)
lambda_plot(mod,lambda = seq(0,2,0.1))
lambda_plot(mod,lambda = seq(0,2,0.1),showplot = FALSE)
