Robj |
The R-object to transfer to HDF5 |
dtype |
Datatype of the HDF5 object. Of class |
nelem |
Number of elements to copy |
flags |
Some flags governing edge cases of conversion from HDF5 to R. This is related to how integers are being treated and
the issue of R not being able to natively represent 64bit integers and not at all being able to represent unsigned 64bit integers
(even using add-on packages). The constants governing this are part of |
id |
When creating a reference, an id for the file (or an object in the file) is needed. By default |
These are the low-level function that dispatch the R object to HDF5 object conversion to the underlying C code.
None of these should be accessed by the end-user under normal circumstances. See also convertRoundTrip
for an example of how to use them.
The converted object or the buffer into which the object is written.
