rcpp_hdf5dataset_write_dimnames

OTHER

1 Description

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

2 Usage

rcpp_hdf5dataset_write_dimnames(ptr_sexp, rownames, colnames)

3 Arguments

Parameter	Description
`ptr_sexp`	External pointer (SEXP) to an open .
`rownames`	Character vector of row names. Use to skip writing row names.
`colnames`	Character vector of column names. Use to skip writing column names.

4 Value

invisibly.
