### Examples

    # construct SCE & run clustering
    data(PBMC_fs, PBMC_panel, PBMC_md, merging_table)
    sce <- prepData(PBMC_fs, PBMC_panel, PBMC_md)
    sce <- cluster(sce)

    # one condition only, remove a single sample
    filterSCE(sce, condition == "Ref", sample_id != "Ref1")

    # keep only a subset of clusters
    filterSCE(sce, cluster_id %in% c(7, 8, 18), k = "meta20")
