Color Map on Correlations

Description

Color Map on Correlations

Usage

alias_matrix(
  design,
  midpoint = 0.5,
  digits = 3,
  color_palette = "viridis",
  alpha = 1,
  direction = 1,
  showplot = TRUE
)

Arguments

design

Design of experiment (Without response)

midpoint

A midpoint value between (0,1) to split the color scheme of three colors

digits

number of digits to round correlation values. Default is 3

color_palette

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

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 correlation plot. If false, the correlation/alias matrix is returned. Default is TRUE

Value

correlation matrix between main effects and interaction effects from the model.matrix. Alias matrix is also returned

Examples

alias_matrix(design=aliased_design)
alias_matrix(design=aliased_design, color_palette = "plasma")
alias_matrix(design=aliased_design, color_palette = "magma", direction = -1)
