h5mread

h5mread reads arbitrary data from an HDF5 dataset into R with optimized speed and memory efficiency.

Key Features:

• Fast HDF5 reading: The h5mread() function provides optimized performance for reading data from HDF5 datasets compared to existing alternatives.
• Memory efficiency: The implementation minimizes memory overhead when loading HDF5 data into R.
• Arbitrary data access: Supports reading any data subset from an HDF5 dataset without loading the entire file.

Scientific Applications:

• Large-scale data analysis: Enables efficient access to large HDF5-formatted datasets commonly used in bioinformatics and genomics research.

Methodology:

The h5mread() function implements an optimized C-based backend for HDF5 data extraction into R, analogous to h5read() from the rhdf5 package but with improved performance characteristics.
