rcpp_hdf5dataset_read_dimnames R Documentation
Read dimension names (rownames / colnames) from an HDF5 dataset
Description
Reads the row and column names stored alongside an HDF5 dataset following
the BigDataStatMeth convention:
rownames stored at group/.<dataset>_dimnames/1
colnames stored at group/.<dataset>_dimnames/2
When a component has not been written an empty character(0) is
returned for it. The function uses BigDataStatMeth::hdf5Dims in
read mode (bWrite = false) so no data on disk is modified.
Usage
rcpp_hdf5dataset_read_dimnames(ptr_sexp)
Arguments
ptr_sexp
External pointer (SEXP) to an open hdf5Dataset
object managed by the R6 class.
Value
Named list with two character elements:
- rownames
Row names, or character(0) if absent
- colnames
Column names, or character(0) if absent
