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")
