Load cells example data into a MemoryDaf.

Replicates the Julia ExampleData.example_cells_daf() dataset. Data are loaded from the bundled inst/extdata/example_data/ files and type-promoted using the same lattice as Julia (Bool → UInt32/Int32 → Float32 for vectors; UInt8 → UInt16 → Float32 for matrices).

Usage

example_cells_daf(name = "cells!")

Arguments

name

Name for the returned MemoryDaf.

Value

A MemoryDaf pre-populated with 856 cells, 683 genes, 95 donors, and 23 experiments.
