peakPantheR_loadAnnotationParamsCSV: Load fit parameters from CSV

In peakPantheR: Peak Picking and Annotation of High Resolution Experiments

Description

Initialise a new peakPantheRAnnotation object after loading ROI, uROI and FIR parameters from CSV. spectraPaths, spectraMetadata or cpdMetadata are not initialised and will need to be filled before annotation. useUROI and useFIR are set to FALSE and will need to be set accordingly. uROIExist is established depending on the uROI columns present in the CSV and will be set to TRUE only if no NA are present

Usage

peakPantheR_loadAnnotationParamsCSV(CSVParamPath, verbose = TRUE)

Arguments

CSVParamPath	(str) Path to a CSV file of fit parameters (e.g. as saved by outputAnnotationDiagnostic)
verbose	(bool) If TRUE message progress

Value

(peakPantheRAnnotation) Object initialised with ROI, uROI and FIR read from the CSV file

#  2 compounds in 0 samples.
#   updated ROI exist (uROI)
#   does not use updated ROI (uROI)
