Plot heatmap

Usage

plotHeatmap(
  x,
  genes = rownames(x),
  color = "darkblue",
  assays = colnames(x),
  useFillScale = TRUE
)

# S4 method for class 'cellSpecificityValues'
plotHeatmap(
  x,
  genes = rownames(x),
  color = "darkblue",
  assays = colnames(x),
  useFillScale = TRUE
)

# S4 method for class 'data.frame'
plotHeatmap(
  x,
  genes = rownames(x),
  color = "darkblue",
  assays = colnames(x),
  useFillScale = TRUE
)

# S4 method for class 'matrix'
plotHeatmap(
  x,
  genes = rownames(x),
  color = "darkblue",
  assays = colnames(x),
  useFillScale = TRUE
)

Arguments

x: fractions for each gene
genes: name of genes to plot
color: color of heatmap
assays: array of assays to plot
useFillScale: default TRUE. add scale_fill_gradient() to plot

Value

heatmap

Examples

library(muscat)
library(SingleCellExperiment)

data(example_sce)

# create pseudobulk for each sample and cell cluster
pb <- aggregateToPseudoBulk(example_sce,
  assay = "counts",
  cluster_id = "cluster_id",
  sample_id = "sample_id",
  verbose = FALSE
)

# Compute cell type specificity of each gene
df <- cellTypeSpecificity(pb)

# For each cell type, get most specific gene
genes <- rownames(df)[apply(df, 2, which.max)]

# heatmap of 5 genes that are most cell type specific
dreamlet::plotHeatmap(df, genes = genes)
