Changes in version 1.4.0                        

    o   Migrated all of the dataset getter functions to the celldex
	package.

    o   Streamlined the vignette to point to the book at <URL:
	http://bioconductor.org/books/devel/SingleRBook/>.

    o   Added a restrict= argument to trainSingleR() and SingleR() to
	easily restrict to a subset of features.

    o   Deprecated the method= argument in SingleR().

    o   Protect against accidental data.frames in ref= or test= in all
	functions.

                        Changes in version 1.2.0                        

    o   Added support for consolidating labels from multiple references
	via combineResults().

    o   Added mappings to standardized Cell Ontology terms in all
	*Data() functions.

    o   Changed the name of the labels input of plotScoreDistribution()
	to labels.use for consistency across functions.

    o   Fixed a label from adipocytes to astrocytes in
	BlueprintEncodeData().

    o   Removed umlauts from labels (e.g., naive) in
	NovershternHematopoieticData() to avoid problems with Windows.

    o   Perform PCA before clustering in aggregateReference() for speed
	and memory efficiency.

    o   Modified genes="all" behavior in trainSingleR() to report
	DE-based markers for fine-tuning only.

                        Changes in version 1.0.0                        

    o   New package SingleR for cell type annotation.
