Bioc currentBring Zarr datasets in R as DelayedArray objects
Release Lineage
Entered 3.23 · Apr 29, 2026
Current · Requires R 4.6
Description
The ZarrArray package leverages the Rarr package to bring Zarr datasets in R as DelayedArray objects. The main class in the package is the ZarrArray class. A ZarrArray object is an array-like object that represents a Zarr dataset in R. ZarrArray objects are DelayedArray derivatives and therefore support all operations (delayed or block-processed) supported by DelayedArray objects.
