spillover_heatmap: Spillover heatmap

In cellGeometry: Geometric Single Cell Deconvolution

Spillover heatmap

Description

Produces a heatmap from a 'cellMarkers' or 'deconv' class object showing estimated amount of spillover between cell subclasses. The amount that each cell subclass's overall vector spillovers (projects) into other cell subclasses' vectors is shown in each row. Thus the column gives an estimate of how much the most influential (specific) genes for a cell subclass are expressed in other cells.

Usage

spillover_heatmap(
  x,
  text = NULL,
  cutoff = 0.5,
  fontsize = 8,
  subset = NULL,
  ...
)

Arguments

x	Either a 'cellMarkers' or 'deconv' class object or a spillover matrix.
text	Logical whether to show values of cells where spillover > cutoff. By default only shown for smaller matrices.
cutoff	Threshold for showing values.
fontsize	Numeric value for font size for cell values when text = TRUE.
subset	Character vector of groups to be subsetted.
...	Optional arguments passed to ComplexHeatmap::Heatmap().

Value

No return value. Draws a heatmap using ComplexHeatmap.
