GetArea: Get LC-MS Area signals

In Yaroslav-Lyutvinskiy/MZAccessR: R Interface to mzAccess Web-API

Description

Gets all non-zero signals for specified LC-MS area. Corresponds to mzAccess web-service API function GetArea

Usage

GetArea(FileName, MZLow, MZHigh, RTLow, RTHigh, Cache = TRUE,
  Profile = FALSE)

Arguments

FileName	- Name of original raw mass spectrometry file. Can be stated with or without path and extention
MZLow	- Minimum m/z value for LC-MS area requested
MZHigh	- Maximum m/z value for LC-MS area requested
RTLow	- Minimum retention time value for LC-MS area requested
RTHigh	- Maximum retention time value for LC-MS area requested
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

Value

Data frame of Mass, Retention Time and Intensities for requested LC-MS area

Examples

GetArea(FileName="Thermo_QE_cells_72h_UL_1",149.047,149.074, RTLow = 8.2, RTHigh = 8.5,Profile = TRUE, Cache = FALSE)
