Generates tree-like data with branches

Generates synthetic data that has a tree-like structure to simulate evolution/trajectory of data.

Usage

rs_data_trajectory(n_samples, dim, topology, cell_trajectories, noise, seed)

Arguments

n_samples

Integer. Number of data points to generate.

dim

Integer. Dimensionality of the data.

topology

String. One of c("bifurcation", "linear", "combination").

cell_trajectories

List or NULL. Named list with three equal-length vectors: parent (integer, NA for root, zero-indexed), split_at (numeric, fraction along parent where branch starts), and length (numeric, length of the branch). If NULL, will use the topology specified in topology.

noise

Numeric. How much noise to add.

seed

Integer. For reproducibility purposes.

Value

A list with the following elements:

• data - Numerical matrix with the generated data.

• branches - Branch assignments for each sample.
