Heatmap of specific genes

Given a set of markers, plot their expression across clusters on a heatmap.

PlotClusterExpression(
  data,
  cluster_labels,
  y_lsize = (length(unique(cluster_labels))/8) * 7,
  y_tsize = (length(unique(cluster_labels))/8) * 7,
  x_lsize = (length(unique(cluster_labels))/8) * 7,
  x_tsize = (length(unique(cluster_labels))/8) * 7,
  lti_size = (length(unique(cluster_labels))/8) * 7,
  lt_size = (length(unique(cluster_labels))/8) * 7,
  markers,
  use_z = TRUE
)

Arguments

data	expression data with genes x cells
cluster_labels	a vector of cluster labels corresponding to the columns in the data matrix
y_lsize	y axis label size
y_tsize	y axis title size
x_lsize	x axis label size
x_tsize	x axis title size
lti_size	size of legend title
lt_size	size of legend text
markers	a vector of markers
use_z	use z-score per gene instead of raw expression

Value

a grid plot
