plotDistDoF function

Degrees of freedom plot for both distances

Shows a plot with degrees of freedom computed for score and orthogonal distances at given number of components using data driven approach ("ddmoments" or "ddrobust").

plotDistDoF(
  obj,
  type = "b",
  labels = "values",
  xticks = seq_len(obj$ncomp),
  ...
)

Arguments

• obj: a PCA model (object of class pca)
• type: type of the plot ("b", "l", "h")
• labels: what to show as data points labels
• xticks: vector with tick values for x-axis
• ...: other plot parameters (see mdaplotg for details)

Details

Work only if parameter lim.type equal to "ddmoments" or "ddrobust".
