Calculate meta cell purity

A potential metric to see how well the meta cells are aggregated is their cell type purity. This helper function helps to plot the meta-cell purity based on annotated cell types. These can be also just unsupervised memberships to graph-based clustering, etc.

Usage

calc_meta_cell_purity(object, original_cell_type)

Arguments

object

MetaCells class.

original_cell_type

Character vector. The original cell type annotations. The indices need to match with the original cell indices used to generate the meta-cells! (1-indexed)

Value

The MetaCells with an added columns to the observation table with the purity measures
