### Examples

    N0 = 10
    G <- 1000
    GDEp <- 50
    GDEn <- 50

    set.seed(15213)

    astudy <- matrix(rpois(N0*2*G,10),nrow=G,ncol=N0*2)
    ControlLabel <- 1:N0
    caseLabel <- (N0 + 1):(2*N0)

    astudy[1:GDEp,caseLabel] <- astudy[1:GDEp,caseLabel] + 2
    astudy[1:GDEp + GDEn,caseLabel] <- astudy[1:GDEp,caseLabel] - 2

    alabel <- c(rep(0,length(ControlLabel)),rep(1,length(caseLabel)))
    Study <- list(data=astudy, label=alabel)

    result <- function_edgeR(Study)
    fdr <- p.adjust(result$pvalue)
    sum(fdr<=0.05)
