  axis_text_y_size = 6,
  show_plot = NA,
  return_plot = NA,
  save_plot = NA,
  save_param = list(),
  default_save_name = "violinPlot"
)

Examples

data(mini_giotto_single_cell)

# get all genes
all_genes = slot(mini_giotto_single_cell, 'gene_ID')

# look at cell metadata
cell_metadata = pDataDT(mini_giotto_single_cell)

# plot violinplot with selected genes and stratified for identified cell types
violinPlot(mini_giotto_single_cell,
genes = all_genes[1:10],
cluster_column = 'cell_types')
