addPerCellQC {scater} | R Documentation

## Add QC to an SE

### Description

Convenient utilities to compute QC metrics and add them to a SummarizedExperiment's metadata.

### Usage

    addPerCellQC(x, ...)

    addPerFeatureQC(x, ...)

### Arguments

`x` | A SummarizedExperiment object or one of its subclasses.
`...` | For `addPerCellQC`, further arguments to pass to `perCellQCMetrics`. For `addPerFeatureQC`, further arguments to pass to `perFeatureQCMetrics`.

### Details

These functions are simply wrappers around `perCellQCMetrics` and `perFeatureQCMetrics`, respectively. The computed QC metrics are automatically appended onto the existing `colData` or `rowData`. No protection is provided to avoid duplicated column names.

### Value

An object like `x` but with the QC metrics added to the row or column metadata.

### Examples

    example_sce <- mockSCE()
    example_sce <- addPerCellQC(example_sce)
    colData(example_sce)

    example_sce <- addPerFeatureQC(example_sce)
    rowData(example_sce)
