Color Map on Correlations

Usage

alias_matrix(
  design,
  midpoint = 0.5,
  digits = 3,
  color_palette = "viridis",
  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"
showplot: logical indicating to show the correlation plot. If false, the correlation/alias matrix is returned. Default is TRUE
...: additional parameters to be given to viridisPalette, such as alpha and direction

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)
