GetAreaArray: Get Array of LC-MS Area signals
In Yaroslav-Lyutvinskiy/MZAccessR: R Interface to mzAccess Web-API

Description Usage Arguments Value Examples

Batch analog of GetArea function. Gets List of data frames where each data frame contains all non-zero signals for one of specified LC-MS areas. Equal length of incoming lists is assumed. Corresponds to mzAccess web-service API function GetAreasArray

1 2	GetAreaArray(FileNames, MZLows, MZHighs, RTLows, RTHighs, Cache = TRUE, Profile = FALSE)

`FileNames`	- List of names of original raw mass spectrometry file.
`Cache`	- If TRUE data will be loaded from fast access cache, if FALSE - from original raw files
`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
`MZLow`	- List of minimum m/z values for LC-MS areas requested
`MZHigh`	- List of maximum m/z values for LC-MS areas requested
`RTLow`	- List of minimum retention time values for LC-MS areas requested
`RTHigh`	- List of maximum retention time values for LC-MS areas requested

List of data frames. Each n-th data frame contains Mass, Retention Time and Intensities for all non-zero signals for LC-MS area, specified by n-th members of incoming arrays.
