Each of the letters separated by the character "_" corresponds to a class value. Classes having the same letters are indistinguible whereas those having different letters are statistically different clases. } \item{ The last columns contain the mean and median values for each feature } } } \seealso{ \code{\link{spectralTStudent}} \code{\link{spectralAnova}} } \examples{ data(MAIT_sample) MAIT<-spectralSigFeatures(MAIT,p.adj="fdr",parametric=TRUE) head(sigPeaksTable(MAIT)) } \author{Francesc Fernandez, \email{[email protected]}} \keyword{file}
