GetSpectrumArray: Get Array of averaged spectra
In Yaroslav-Lyutvinskiy/MZAccessR: R Interface to mzAccess Web-API

Description Usage Arguments Value Examples

Batch analog of GetAveSpectrum function. Get Array of spectra averaged (or summed) within desired RT intervals Corresponds to mzAccess web-service API function GetSpectrumArray Equal length of incoming lists is assumed. Averaging algorithm is vendor specific, therefore function has no cache option

1	GetSpectrumArray(FileNames, MZLows, MZHighs, RTLows, RTHighs, Profile = FALSE)

`Profile`	- If TRUE data will presented in profile mode how is was acquired by mass spectrometer, If FALSE data will be presented in peak centroided mode
`FileName`	- Name of original raw mass spectrometry file. Can be stated with or without path and extention
`MZLow`	- List of minimum m/z values to be included in spectrum
`MZHigh`	- List of maximum m/z values to be included in spectrum
`RTLow`	- List of minimum retention time values for RT range of averaged spectrum
`RTHigh`	- List of maximum retention time values for RT range of averaged spectrum

List of data frames of Mass and Intensities for requested averaged spectra
