Draw treemap

Draw treemap which shows the number and percentage of cells with 0, 1, 2, etc. clone barcodes.

draw_treemap(
  cell_by_clone_matrix,
  valid_cells_bcodes,
  cell_bcode_col = "CellBarcode"
)

Arguments

cell_by_clone_matrix

A data.table where each row denotes a cell, a clone barcode, and the number of reads assigned to the clone.

valid_cells_bcodes

A character vector of cell barcodes for droplets deemed real cells. Can be the cell barcodes in cell by gene matrix generated by cellranger's filtered count matrix.

cell_bcode_col

The column in cell_by_clone_matrix denoting the cell's barcode.

Value

A ggplot object containing the treemap.

Examples

library(data.table)

cell_by_clone_matrix <- data.table(
    CellBarcode = c("A", "B", "C", "C"),
    CloneBarcode = c("AA", "AA", "BB", "CC"),
    n_reads = as.integer(c(2, 2, 2, 1))
)
draw_treemap(
    cell_by_clone_matrix = cell_by_clone_matrix,
    valid_cells_bcodes = c("A", "B", "C")
)
