Build a small example VISTA object — example

Creates a lightweight VISTA object from built-in package datasets (count_data and sample_metadata) for use in examples and tutorials. The default call returns a precomputed object to keep examples and package checks fast. Non-default argument combinations fall back to rebuilding the object from the packaged example inputs.

Usage

example_vista(n_genes = 150, n_per_group = 3, method = "deseq2")

Arguments

n_genes: Number of genes to include (default 150).
n_per_group: Number of samples per group (control and treatment1) to include (default 3).
method: Differential expression backend passed to create_vista().

Value

A VISTA object.
