HTOHeatmap: Hashtag oligo heatmap

In atakanekiz/Seurat3.0: Tools for Single Cell Genomics

Description

Draws a heatmap of hashtag oligo signals across singlets/doublets/negative cells. Allows for the visualization of HTO demultiplexing results.

Usage

HTOHeatmap(object, assay = "HTO", classification = paste0(assay,
  "_classification"), global.classification = paste0(assay,
  "_classification.global"), ncells = 5000, singlet.names = NULL)

Arguments

object	Seurat object. Assumes that the hash tag oligo (HTO) data has been added and normalized, and demultiplexing has been run with HTODemux().
assay	Hashtag assay name.
classification	The naming for metadata column with classification result from HTODemux().
global.classification	The slot for metadata column specifying a cell as singlet/doublet/negative.
ncells	Number of cells to plot. Default is to choose 5000 cells by random subsampling, to avoid having to draw exceptionally large heatmaps.
singlet.names	Namings for the singlets. Default is to use the same names as HTOs.

Value

Returns a ggplot2 plot object.
