tsnehm: Compute t-SNE Heatmap
In JulianSpagnuolo/FACkit: FACS Analysis Tool Kit

Experimental version of t-SNE heatmaps codes

1 2	tsnehm(data, markers, tsne_embedding, cell_labels, breaks = 100, plot = TRUE)

`markers`	markers of interest
`tsne_embedding`	1D t-SNE embedding
`cell_labels`	Labels for each cell. Typically these are the cluster assignments for each cell, as obtained by dbscan on the 2D t-SNE. This way, the columns of the heatmap will have a color assigned to each of them, and they can be mapped to a corresponding location on the 2D t-SNE
`breaks`	Number of bins
`plot`	Logical. Whether to plot the heatmap (TRUE). If false, a list containing a matrix of the heatmap data and the column annotations (group_label) will be returned. Default is TRUE
`expression_matrix`	FACS data. Columns should be markers, rows are cells.
