Read all attributes from a given location in an HDF5 file

Usage

h5readAttributes(file, name, native = FALSE, ...)

Arguments

file: Character vector of length 1, giving the path to the HDF5
name: Path within the HDF5 file to the object whose attributes should be read. The datasets present in file can be listed with the function h5ls().
native: An object of class logical. If TRUE, array-like objects are treated as stored in HDF5 row-major rather than R column-major orientation.
...: Further arguments passed to H5Aread().

Value

A named list of the same length as the number of attributes attached to the specific object. The names of the list entries correspond to the attribute names. If no attributes are found an empty list is returned.

Examples

h5File <- tempfile(pattern = "ex_createAttribute.h5")
h5createFile(h5File)
h5write(1:1, h5File, "A")
fid <- H5Fopen(h5File)
did <- H5Dopen(fid, "A")
h5createAttribute(did, "time", c(1, 10))
#> [1] TRUE
h5readAttributes(h5File, "A")
#> Warning: An open HDF5 file handle exists. If the file has changed on disk meanwhile, the function may not work properly. Run 'h5closeAll()' to close all open HDF5 object handles.
