## Find areas of high peak density in LC/MS Data

### Description

### Arguments

`object` | `xcmsRaw-class` object
`massrange` | Not implemented.
`scanrange` | scan range to check for peaks
`dev` | maximum width of m/z box in ppm
`minEntries` | minimum number of peaks(centroids) within the range of `dev` ppm

### Details

Areas of high peak density (characterised by having at least `minEntries` peaks within `dev` ppm in consecutive scans) in the LC/MS map are located.

### Value

A list with entries :

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

### Methods

object = "xcmsRaw"
  `findMZBoxes(object, massrange=c(0.0,0.0), scanrange=c(1,length(object@scantime)), dev, minEntries)`
