plotQDoF: Degrees of freedom plot for orthogonal distance (Nh)

In mdatools: Multivariate Data Analysis for Chemometrics

Degrees of freedom plot for orthogonal distance (Nh)

Description

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

Usage

plotQDoF(
  obj,
  type = "b",
  labels = "values",
  xticks = seq_len(obj$ncomp),
  ylab = "Nq",
  ...
)

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
ylab	label for y-axis
...	other plot parameters (see mdaplotg for details)

Details

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