ChromBackendMemory: Improved in-memory Chromatographic data backend

In rformassspectrometry/Chromatograms: Infrastructure for Chromatographic Mass Spectrometry Data

Improved in-memory Chromatographic data backend

Description

ChromBackendMemory: This backend stores chromatographic data directly in memory, making it ideal for small datasets or testing. It can be initialized with a data.frame of chromatographic data via the chromData parameter and a list of data.frame entries for peaks data using the peaksData parameter. These data can be accessed with the chromData() and peaksData() functions.

Usage

ChromBackendMemory()

## S4 method for signature 'ChromBackendMemory'
backendInitialize(
  object,
  chromData = fillCoreChromVariables(data.frame()),
  peaksData = list(.EMPTY_PEAKS_DATA)
)

Arguments

object	A ChromBackendMemory object.
chromData	For backendInitialize() of a ChromBackendMemory backend, a data.frame with the chromatographic data. If not provided (or if empty), a default data.frame with the core chromatographic variables will be created.
peaksData	For backendInitialize() of a ChromBackendMemory backend, a list of data.frame with the peaks data. If not provided (or if empty), a default list of empty data.frame with the core peaks variables will be created. The length of the list should match the number of chromatograms in the chromData parameter.
