dilutionCorrection: A function for scaling to individual dilution factors.

In mrbin: Metabolomics Data Analysis Functions

A function for scaling to individual dilution factors.

Description

This function performs sample-wise scaling of binned data to correct for dilution through different sample volumes used, or for different sample weights. All bin values of one sample are multiplied by the corresponding dilution factor.

Usage

dilutionCorrection(mrbinResults, verbose = TRUE, errorsAsWarnings = FALSE)

Arguments

mrbinResults	An mrbin object
verbose	Should a summary be printed?
errorsAsWarnings	If TRUE, errors will be turned into warnings. Should be used with care, as errors indicate undocumented changes to the data.

Value

An invisible mrbin object containing scaled NMR data.

Examples

mrbinResults<-mrbin(silent=TRUE,setDefault=TRUE,parameters=list(dimension="1D",
         binwidth1D=0.05,PQNScaling="No",PCA="No",tryParallel=FALSE,logTrafo="No",
         NMRfolders=c(system.file("extdata/1/10/pdata/10",package="mrbin"),
                      system.file("extdata/2/10/pdata/10",package="mrbin"),
                      system.file("extdata/3/10/pdata/10",package="mrbin"))),
         metadata=list(dilutionFactors=c(.75,1,.5)))
mrbinResults<-dilutionCorrection(mrbinResults)
