rsd_filter: RSD filter

In structToolbox: Data processing & analysis tools for Metabolomics and other omics

Description

An RSD filter calculates the relative standard deviation (the ratio of the mean to the standard deviation) for all features. Any feature with an RSD lower than a predefined threshold is excluded.

Usage

rsd_filter(rsd_threshold = 20, qc_label = "QC", factor_name, ...)

Arguments

rsd_threshold	(numeric) The RSD threshold below which features are removed. The default is 20.
qc_label	(character) The label used to identify QC samples. The default is "QC".
factor_name	(character) The name of a sample-meta column to use.
...	Additional slots and values passed to struct_class.
