## Get average m/z and intensity values for multiple mass scans

### Description

Return full-resolution averaged data from multiple mass scans.

### Arguments

`object` | the `xcmsRaw` object
`...` | arguments passed to `profRange` used to sepecify the spectral segments of interest for averaging

### Details

Based on the mass points from the spectra selected, a master unique list of masses is generated. Every spectra is interpolated at those masses and then averaged.

### Value

A matrix with two columns:

`mz` | m/z values
`intensity` | intensity values

### Methods

object = "xcmsRaw"
  `getSpec(object, ...)`
