metadata: Access the metadata from an 'mzR' object.

In sneumann/mzR-playground: parser for netCDF, mzXML, mzData and mzML files (mass spectrometry data)

Description

Accessors to the analytical setup metadata of a run. runInfo will show a summary of the experiment as a named list, including scanCount, lowMZ, highMZ, startMZ, endMZ, dStartTime and dEndTime. The instrumentInfo method returns a named list including instrument manufacturer, model, ionisation technique, analyzer and detector. These individual pieces of information can also be directly accessed by the specific methods.

Usage

runInfo(object)
analyzer(object)
detector(object)
instrumentInfo(object)
ionisation(object)
manufacturer(object)
model(object)

Arguments

object

An instantiated mzR object.
