In cbroeckl/RAMClustR: Mass Spectrometry Metabolomics Feature Clustering and Interpretation

rc.remove.qc

Description

summarize quality control for clustering and for quality control sample variation based on compound ($SpecAbund) and feature ($MSdata and $MSMSdata, if present)

Usage

rc.remove.qc(ramclustObj = NULL, qc.tag = "QC")

Arguments

ramclustObj	ramclustR object to analyze
qc.tag	qc.tag character vector of length one or two. If length is two, enter search string and factor name in $phenoData slot (i.e. c("QC", "sample.type"). If length one (i.e. "QC"), will search for this string in the 'sample.names' slot by default.

Details

simply moves QC samples out of the way for downstream processing. moved to a $qc slot.

Value

new RC object. moves QC samples to new $qc slot from original position.
