Prepare Data for Plotting

Usage

prepare(
  x,
  margin,
  axes = c(1, 2),
  active = TRUE,
  sup = TRUE,
  principal = TRUE,
  highlight = NULL,
  reorder = TRUE,
  color = NULL,
  fill = NULL,
  shape = 16,
  size = c(1, 3),
  line_type = NULL,
  line_width = size,
  ...
)

Arguments

x: A MultivariateAnalysis object.
margin: A length-one numeric vector giving the subscript which the data will be returned: 1 indicates individuals/rows (the default), 2 indicates variables/columns.
axes: A length-two numeric vector giving the dimensions to be plotted.
active: A logical scalar: should the active observations be plotted?
sup: A logical scalar: should the supplementary observations be plotted?
principal: A logical scalar: should principal coordinates be returned? If FALSE, standard coordinates are returned.
highlight: A vector specifying the information to be highlighted. If NULL (the default), no highlighting is applied. If a single character string is passed, it must be the name of a categorical variable, or one of "observation", "mass", "sum", "contribution" or "cos2" (see augment()).
color: The colors for lines and points (will be mapped to highlight).
shape: A vector of plotting characters or symbols (will be mapped to highlight). This can either be a single character or an integer code for one of a set of graphics symbols.
size: A length-two numeric vector giving range of possible sizes (greater than 0; (will be mapped to highlight).
line_type, line_width: A specification for the line type and width (will be mapped to highlight).

Value

A data.frame with the following columns:

x: Coordinates along x.
y: Coordinates along y.
z: Variable to be highlighted.
label: Label.
sup: Is supplementary?
col: Color for lines and points.
bg: Background color.
pch: Symbol.
cex: Symbol size.
lty: Line type.
lwd: Line width.
