Biological feature (such as gene) selection based on the most variant Median Absolute Deviation (MAD).

Description

Biological feature (such as gene) selection based on the most variant Median Absolute Deviation (MAD).

Usage

FSbyMAD(Data, cut.type = "topk", value)

Arguments

Data

A data matrix representing the genomic data measured in a set of samples. For the matrix, the rows represent the genomic features, and the columns represents the samples.

cut.type

A character value representing the selection type. The optional values are shown below:

  • "topk"

  • "cutoff"

value

A numeric value.
If the cut.type="topk", the top number of value features are selected.
If the cut.type="cutoff", the features with (MAD>value) are selected.

Value

An extracted subset data matrix with the most variant MAD features from the input data matrix.
