Defaults to TRUE.} \item{\dots}{additional parameters for functions \code{\link[stats]{t.test}}, \code{\link[stats]{wilcox.test}} or \code{\link{bootstrapT}}.} } \value{ The result of this function is an object of class \code{\link{maigesDE}} if \code{doClust} if FALSE or of class \code{\link{maigesDEcluster}} if it is TRUE. } \details{ This function calculate t statistics and p-values by re-sampling of the data using the function \code{\link{bootstrapT}}. There is the option to do the t test directly, using the function \code{\link{deGenes2by2Ttest}}, or to do the non-parametric Wilcox test using the function \code{\link{deGenes2by2Wilcox}}. } \seealso{ \code{\link{bootstrapT}}, \code{\link{deGenes2by2Ttest}} and \code{\link{deGenes2by2Wilcox}}. } \examples{ ## Loading the dataset data(gastro) ## Doing bootstrap from t statistic test fot 'Type' sample label, k=1000 ## specifies one thousand bootstraps gastro.boot = deGenes2by2BootT(gastro.summ, sLabelID="Type", k=1000) gastro.boot } \author{ Gustavo H.
