The list of aligned metabolites and their relative quantification for each sample in a given experiment
Usage
alignList(object, by.area=TRUE)
Arguments
object
A 'MetaboSet' S4 object containing the experiment data. The experiment has to be previously deconvolved, aligned and (optionally) identified.
by.area
if TRUE (default), eRah outputs quantification by the area of the deconvolved chromatographic peak of each compound. If FALSE, eRah outputs the intensity of the deconvolved chromatographic peak.
Value
alignList returns an S3 object:
AlignIDThe unique Tag for found metabolite by eRah. Each metabolite found by eRah for a given experiment has an unique AlignID tag number.
Factorthe Factor tag name. Each metabolite has an unique 'Factor' name to enhance visual interpretation.
tmeanThe mean compound retention time.
FoundInThe number of samples in which the compound has been detected (the number of samples where the compound area is non-zero).
QuantificationAs many columns as samples and as many rows as metabolites, where each column name has the name of each sample.
Details
Returns an alignment table containing the list of aligned metabolites and their relative quantification for each sample in a given experiment.
