\name{spectralWilcox} \alias{spectralWilcox} \title{Extract significant features from a MAIT object} \description{ Function spectralWilcox takes an \code{\link{MAIT-class}} object and obtains which of the variables are significant given a p-value threshold following a Mann-Witney-Wilcoxon test. The parameters of the significant features can ve printed to an output table (TRUE by default). } \usage{ spectralWilcox(MAIT.object = NULL, pvalue = 0.05, p.adj="none", printCSVfile = TRUE, jitter = FALSE, jitter.factor = 1, jitter.amount = 0) } \arguments{ \item{MAIT.object}{ A \link{MAIT-class} object where function \link{peakAggregation} has already been applied. The output of the function is going to be an update of the same \link{MAIT-class} object. } \item{pvalue}{ P-value threshold. Variables having a p-value lower than this value is considered as a significant variable. } \item{p.adj}{ Post-hoc method to be used to correct the p-values. } \item{printCSVfile}{ Set to TRUE if an output table has to be produced. See function \link{sigPeaksTable} for more information. } \item{jitter}{ If it is set to TRUE, a jitter noise is added to the data. This is useful when applying Mann-Whitney tests with ties. } \item{jitter.factor}{ See argument factor of the function \link{jitter}. } \item{jitter.amount}{ See argument amount of the function \link{jitter}. } } \value{ A \link{MAIT-class} object containing the significant features of the scores slot of \link{MAIT-class} object used as an input. } \seealso{ \code{\link{MAIT-class}} \code{\link{peakAggregation}} \code{\link{sigPeaksTable}} } \author{Francesc Fernandez, \email{[email protected]}} \keyword{internal}
