mrbin (version 1.9.4)

removeNoise: A function for removing bins below noise level.

Description

This function checks for each bin (column) whether its level is below the individual noise level times the signal-to-noise ratio. If less than the defined threshold level are above noise*SNR, the whole bin is removed.

Usage

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

Value

An invisible mrbin object

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.

Examples

resetEnv()#clean up previous data from the package environment 
results<-mrbin(silent=TRUE,setDefault=TRUE,parameters=list(dimension="1D",
                   binwidth1D=0.05,noiseRemoval="No",PQNScaling="No",
                   fixNegatives="No",logTrafo="No",PCA="No",verbose=TRUE,
