variableGenes {MetaNeighbor} | R Documentation

## Identify a highly variable gene set

### Description

Identifies genes with high variance compared to their median expression (top quartile) within each experimentCertain function

### Usage

    variableGenes(dat, i = 1, exp_labels)

### Arguments

`dat` | SummarizedExperiment object containing gene-by-sample expression matrix.
`i` | default value 1; non-zero index value of assay containing the matrix data
`exp_labels` | character vector that denotes the source (Study ID) of each sample.

### Value

The output is a vector of gene names that are highly variable in every experiment (intersect)

### Examples

    data(mn_data)
    var_genes = variableGenes(dat = mn_data, exp_labels = mn_data$study_id)
    var_genes
