Package: lstar Title: Uniform Data Model and 'Zarr' Interchange for Single-Cell Omics Version: 0.2.1 Date: 2026-07-22 Authors@R: person("Peter", "Kharchenko", role = c("aut", "cre"), email = "pk.restricted@gmail.com") Description: A lightweight interchange layer for single-cell and spatial omics data, built on the L-star model of labelled axes and typed fields over them, serialized to the 'Zarr' format. Provides bidirectional converters ("profiles") for 'Seurat', 'SingleCellExperiment', 'Conos', and 'pagoda2' objects, including collections of heterogeneous samples, via a shared C++ core ('libstar') so the same store is readable from R, 'Python', and C++.
