Extract obs/var names from an AnnData object

Cell and feature names on AnnData objects are Python pandas Indexes; R's `rownames()`/`colnames()` do not return them reliably. This helper coerces them to character vectors via Python's `list()` builtin, falling back to `names()` if that path fails.

Usage

anndata_names(adata)

Arguments

adata

An AnnData object (e.g. as returned by `anndata::read_h5ad`).

Value

A list with elements `obs_names` (cells) and `var_names` (features), each a character vector or `NULL` if extraction failed.
