pca_dstat_plot: d-statistic plot

In computational-metabolomics/structtoolbox: Data processing & analysis tools for Metabolomics and other omics

d-statistic plot

Description

A bar chart of the d-statistics for samples in the input PCA model. Samples above the indicated threshold are considered to be outlying.

Usage

pca_dstat_plot(number_components = 2, alpha = 0.05, ...)

Arguments

number_components	(numeric) The number of principal components to use. The default is 2.
alpha	(numeric) A confidence threshold for rejecting samples based on the d-statistic. The default is 0.05.
...	Additional slots and values passed to struct_class.

Value

A pca_dstat_plot object. This object has no output slots. See chart_plot in the struct package to plot this chart object.

Inheritance

A pca_dstat_plot object inherits the following struct classes:

⁠[pca_dstat_plot]⁠ >> ⁠[chart]⁠ >> ⁠[struct_class]⁠

Examples

M = pca_dstat_plot(
      number_components = 2,
      alpha = 0.95)

C = pca_dstat_plot()
