Create an AnnData-like facade for a Daf object

Source: R/anndata_facade.R
as_anndata.Rd

Creates a live, read-only facade over a Daf object that provides AnnData-compatible accessors ($X, $obs, $var, $layers, $uns). No data is copied at construction; reads go through to the underlying Daf object on demand, served by dafJuliaWrapper's R-side cache on subsequent calls.

Usage

as_anndata(daf, obs_axis = NULL, var_axis = NULL, x_name = "UMIs")

Arguments

daf

A Daf object

obs_axis

Name of the observations axis. Auto-detected if NULL (tries "cell", then "metacell").

var_axis

Name of the variables axis. Auto-detected if NULL (tries "gene").

x_name

Name of the primary matrix property. If NULL, the first matrix on (obs_axis, var_axis) is used, preferring "UMIs". Defaults to "UMIs".

Value

A DafAnnData R6 object

Examples

if (FALSE) { # \dontrun{
daf <- example_cells_daf()
adata <- as_anndata(daf)
adata$X # primary matrix
adata$obs # observation metadata
adata$var # variable metadata
adata$obs_names # observation names
adata$n_obs # number of observations
} # }
