Functions to Create/Open DataSets in CommonFG
objects
Although DataSet
objects can implicitly be created using
subsetting operators (see CommonFG
) h5 implements more
explicit functions (used by subsetting operators under the hood) to create
and open DataSets
.

|
.Object |
CommonFG; S4 object of class |
datasetname |
character; HDF5 DataSet name to be used. |
data |
object; Object to be stored in HDF5 file, can be either of type vector, matrix or array. |
type |
character; Character specifying data type, can be either one of:
|
dimensions |
integer; Dimensions of dataset to be created. |
chunksize |
integer; Chunksize to be used for dataset. If set to
|
maxdimensions |
integer; Maximum dimensions used for dataset, |
compression |
integer; Default GZIP compression level to be used, from
0 (no compression) to 9 (maximum compression), defaults to |
size |
numeric; Character length for fixed-length string data types. Default value of -1 creates variable-length strings. |
path |
character; Relative path to .Object. |
full.names |
character; Specify if absolute DataSet path names should be returned. |
recursive |
logical; Specify DatSets should be retrieved recursively from .Object. |
follow.links |
logical; Specify if symbolic links should be followed (only applies if recursive = TRUE). |
