## Extract XICs of chromIndices

### Description

Extracts XICs using mz object. Each chromatogram represents a transition of precursor.

### Usage

    extractXIC_group(mz, chromIndices)

### Arguments

`mz` | (mzRpwiz object)
`chromIndices` | (vector of Integers) Indices of chromatograms to be extracted.

### Value
