Usage

H5Aopen(h5obj, name)

H5Aopen_by_name(h5obj, objname = ".", name)

H5Aopen_by_idx(
  h5obj,
  n,
  objname = ".",
  index_type = h5default("H5_INDEX"),
  order = h5default("H5_ITER")
)

Arguments

h5obj: An object of class H5IdComponent representing a H5 object identifier (file, group, or dataset). See H5Fcreate(), H5Fopen(), H5Gcreate(), H5Gopen(), H5Dcreate(), or H5Dopen() to create an object of this kind.
name: The name of the attribute (character).
objname: The name of the object the attribute belongs to.
n: Opens attribute number n in the given order and index. Indexing is C-style, base-0, so the first attribute is opened with n=0.
index_type: See h5const("H5_INDEX") for possible arguments.
order: See h5const("H5_ITER") for possible arguments.

Value

An object of class H5IdComponent representing a H5 attribute identifier.
