Plot a marker priority "tree" for a given cell type (weights order)

This is a simple visualization: markers ordered by weight and connected as a chain ROOT -> marker1 -> marker2 -> ...

Usage

plot_marker_priority_tree(lineage_table, marker_stats, cell_type_name)

Arguments

lineage_table

Tibble with cell_type/pos_markers/neg_markers.

marker_stats

Output of fit_marker_stats().

cell_type_name

Which cell type to plot.

Value

A ggraph/ggplot object (requires igraph + ggraph).

Examples

markers <- c("CD3e", "CD20")
lineage <- data.frame(
  cell_type = "Immune",
  pos_markers = I(list(markers)),
  neg_markers = I(list(character()))
)
marker_stats <- list(
  CD3e = list(weight = 0.9),
  CD20 = list(weight = 0.7)
)
plot_marker_priority_tree(lineage, marker_stats, "Immune")
