SRV {mQTL} | R Documentation

## Statistical Recoupling of Variables

### Description

Base function for dimensionality reduction by statistical recoupling of variables

### Usage

    SRV(X, minsize, correl, clustf = median)

### Arguments

`X` | data matrix
`minsize` | singlet size
`correl` | bucketting resolution
`clustf` | correlation threshold

### Value

A list:

`indicesdebf` | starting border of superclusters
`indicesfinf` | ending border of superclusters
