checkBounds {Autotuner} | R Documentation

## checkBounds

### Description

Recursive function used to find how far a binned feature might extend beyond the boundary of the originally defined TIC peak.

### Usage

    checkBounds(mass, upper = TRUE, mzDb, currentIndex, intensityStorage,
      ppmEst, scans, origBound, header)

### Arguments

`mass` | Specific mass being checked against adjacent scans.
`upper` | A boolean value that tells the algorithm to check indices greater than the entered one. If false, it will check values less thant the entered one.
`mzDb` | A list of data.frames containing the m/z and intensity values from each scan's mass spectra.
`currentIndex` | Numerical index indicating which scan contains feature specific information.
`intensityStorage` | A vector used during recursion to store intensity values as they are added to peak expansion.
`ppmEst` | Scalar numerical value meant to represent the ppm of the instrument.
`scans` | Set of all possible ms1 scans for the sample.
`origBound` | The original scan bound location of the peak.
`header` | A data.fame containing metadata on the sample like spectra type (MS1 vs MS2), retention time, and scan count.

### Value

This function returns the last index the feature is detected.
