Changes in version 1.6.0                        

    o   Add 15 new signatures.

    o   Update the evaluationSignPlot function to return an overall
	goodness score.

    o   Add getSignGenes function to access the signatures gene list.

    o   When multiple signatures are plotted, values are reported in
	z-scores and not rescaled between 0 and 1 as before.

                        Changes in version 1.4.0                        

    o   Add glioCellStateSign function to compute the glioblastoma
	cellular states defined by Neftel C. et al. Cell (2019).

    o   Add whichAssay argument to signature functions to allow the
	user to specify which assay to use for the signature
	computation.

    o   Users can now plot also other signatures not computed with
	signifinder when using the heatmapSignPlot, correlationSignPlot
	and ridgelineSignPlot functions to compare them with the
	signatures computed with signifinder.

                        Changes in version 1.2.1                        

    o   Add evaluationSignPlot function to show some technical
	information of the signatures computed.

    o   Add nametype argument to geneHeatmapSignPlot function to allow
	more gene name ID in data.

    o   The vignette now contains an example with a single-cell dataset
	and an example with a spatial transcriptomics dataset.

                        Changes in version 1.0.0                        

    o   New package signifinder, for implementation of transcriptional
	cancer signatures.
