Examples

    # library(mogsa)
    # loading gene expression data and supplementary data
    data(NCI60_4array_supdata)
    data(NCI60_4arrays)
    # check the dimension of each supplementary data to see how many gene set annotated the data
    sapply(NCI60_4array_supdata, dim)
    # run analysis
    ana <- moa(NCI60_4arrays, proc.row = "center_ssq1", w.data = "inertia", statis = TRUE)
    plot(ana, value="eig")
    # projectin supplementary data
    smoa <- sup.moa(ana, sup=NCI60_4array_supdata, nf=3)
    # heatmap visualize the gene set scores
    heatmap(slot(smoa, "score"))
