Since v3.32.0 edgeR can directly use offsets in its cpm methods, see http://bioconductor.org/packages/release/bioc/news/edgeR/NEWS so one does not need the path via csaw/SummarizedExperiment anymore. Adding as "edgeR::cpm" rather than "cpm" alone since the SingleCellExperiment package masks the cpm function.
