Mean centre

Description

The mean sample is subtracted from all samples in the data matrix. The features in the centred matrix all have zero mean.

Usage

mean_centre(mode = "data", ...)

Arguments

mode	(character) Mode of action. Allowed values are limited to the following: "data": Centring is applied to the data block. "sample_meta": Centring is applied to the sample_meta block. "both": Centring is applied to both the data and the sample_meta blocks. The default is "data".
...	Additional slots and values passed to struct_class.

Value

A mean_centre object with the following output slots:

centred	(DatasetExperiment)
mean_data	(numeric)
mean_sample_meta	(numeric)

Inheritance

A mean_centre object inherits the following struct classes:

⁠[mean_centre]⁠ >> ⁠[preprocess]⁠ >> ⁠[model]⁠ >> ⁠[struct_class]⁠

Examples

M = mean_centre(
      mode = "data")

M = mean_centre()
