celdaProbabilityMap: Probability map for a celda model

In celda: CEllular Latent Dirichlet Allocation

Description

Renders probability and relative expression heatmaps to visualize the relationship between features and cell populations (or cell populations and samples).

Usage

celdaProbabilityMap(sce, ...)

## S4 method for signature 'SingleCellExperiment'
celdaProbabilityMap(
  sce,
  useAssay = "counts",
  altExpName = "featureSubset",
  level = c("cellPopulation", "sample"),
  ncols = 100,
  col2 = circlize::colorRamp2(c(-2, 0, 2), c("#1E90FF", "#FFFFFF", "#CD2626")),
  title1 = "Absolute probability",
  title2 = "Relative expression",
  showColumnNames = TRUE,
  showRowNames = TRUE,
  rowNamesgp = grid::gpar(fontsize = 8),
  colNamesgp = grid::gpar(fontsize = 12),
  clusterRows = FALSE,
  clusterColumns = FALSE,
  showHeatmapLegend = TRUE,
  heatmapLegendParam = list(title = NULL, legend_height = grid::unit(6, "cm"))
)

Arguments

sce	A SingleCellExperiment object returned by celda_C, celda_G, or celda_CG.
...	Additional parameters passed to Heatmap.
useAssay	A string specifying which assay slot to use. Default "counts".
altExpName	The name for the altExp slot to use. Default "featureSubset".
level	Character. One of "cellPopulation" or "Sample". "cellPopulation" will display the absolute probabilities and relative normalized expression of each module in each cell population. level = "cellPopulation" only works for celda_CG sce objects. "sample" will display the absolute probabilities and relative normalized abundance of each cell population in each sample. Default "cellPopulation".
ncols	The number of colors (>1) to be in the color palette of the absolute probability heatmap.
col2	Passed to col argument of Heatmap. Set color boundaries and colors for the relative expression heatmap.
title1	Passed to column_title argument of Heatmap. Figure title for the absolute probability heatmap.
title2	Passed to column_title argument of Heatmap. Figure title for the relative expression heatmap.
showColumnNames	Passed to show_column_names argument of Heatmap. Show column names.
showRowNames	Passed to show_row_names argument of Heatmap. Show row names.
rowNamesgp	Passed to row_names_gp argument of Heatmap. Set row name font.
colNamesgp	Passed to column_names_gp argument of Heatmap. Set column name font.
clusterRows	Passed to cluster_rows argument of Heatmap. Cluster rows.
clusterColumns	Passed to cluster_columns argument of Heatmap. Cluster columns.
showHeatmapLegend	Passed to show_heatmap_legend argument of Heatmap. Show heatmap legend.
heatmapLegendParam	Passed to heatmap_legend_param argument of Heatmap. Heatmap legend parameters.

Value

A HeatmapList object containing 2 Heatmap-class objects
