uniquifyFeatureNames {scater} | R Documentation

## Make feature names unique

### Description

Combine a user-interpretable feature name (e.g., gene symbol) with a standard identifier that is guaranteed to be unique and valid (e.g., Ensembl) for use as row names.

### Usage

    uniquifyFeatureNames(ID, names)

### Arguments

`ID` | A character vector of unique identifiers.
`names` | A character vector of feature names.

### Details

This function will attempt to use `names` if it is unique. If not, it will append the `_ID` to any non-unique value of `names`. Missing `names` will be replaced entirely by `ID`.

The output is guaranteed to be unique, assuming that `ID` is also unique. This can be directly used as the row names of a SingleCellExperiment object.

### Value

A character vector of unique-ified feature names.
