rcpp_hdf5dataset_write_dimnames

Writes row and/or column names for an HDF5 dataset using the existing
open file handle managed by the R6 object. Unlike
<code>bdWrite_hdf5_dimnames()</code>, this function operates through
<code>hdf5Dataset::writeDimnames()</code> so the long-lived R6 handle sees
the changes immediately - no metadata cache staleness.

internal

A framework for 'scalable' statistical computing on large on-disk
matrices stored in 'HDF5' files. It provides efficient block-wise
implementations of core linear-algebra operations (matrix multiplication,
SVD, PCA, and QR decomposition) written in C++ and R, along with building
blocks from which higher-level multivariate methods such as canonical
correlation analysis can be constructed. These building blocks are designed
not only for direct use, but also as foundational components for developing
new statistical methods that must operate on datasets too large to fit in
memory. The package supports data provided either as 'HDF5' files or
standard R objects, and is intended for high-dimensional applications such
as 'omics' and precision-medicine research.
