Recompute the layout of a Bonsai tree — relayout

Lays the finished tree out again without searching. The tree is renumbered on the Rust side, so the inferred ancestors can come back with different node numbers; the leaves, and so the cells, keep theirs.

Usage

relayout_bonsai(
  x,
  layout = c("equal_angle", "equal_daylight", "dendrogram"),
  hyperbolic = FALSE
)

Arguments

x: A BonsaiTree object.
layout: String. One of c("equal_angle", "equal_daylight", "dendrogram").
hyperbolic: Boolean. Project the layout onto the hyperbolic disk.

Value

The BonsaiTree with the new coordinates.

Examples

# the same tree as a dendrogram
sc <- demo_single_cells(
  prepped = FALSE,
  syn_data_params = params_sc_synthetic_data(n_cells = 200L, n_genes = 50L)
)
tree <- bonsai_sc(sc, .verbose = FALSE)
tree <- relayout_bonsai(tree, layout = "dendrogram")
plot(tree)


unlink(sc@dir_data, recursive = TRUE, force = TRUE)
