Draw expression heatmap

draw_heatmap(
  data,
  subset = NULL,
  show_rownames = FALSE,
  title = "Expression dataset",
  log = TRUE,
  profiles = FALSE,
  conditions = NULL
)

Arguments

data: expression dataframe, with genes as rownames and samples as columns
subset: subset of genes to be display
show_rownames: show rownames or not
title: plot title
log: Show log(expression+1) in the heatmap if TRUE, expression if FALSE
profiles: Show expression/mean(expression) for each gene if TRUE, expression if FALSE
conditions: if NULL, shows all the conditions, else if character vector, shows only the required ones

Examples

data("abiotic_stresses")
DIANE::draw_heatmap(abiotic_stresses$normalized_counts, subset = abiotic_stresses$heat_DEGs,
title = "Log expression for DE genes under heat stress")
