h5_save: Saves a one or more objects to an HDF5 file.

In grimbough/rhdf5: R Interface to HDF5

Saves a one or more objects to an HDF5 file.

Description

Saves a number of R objects to an HDF5 file.

Usage

h5save(..., file, name = NULL, createnewfile = TRUE, native = FALSE)

Arguments

...	The objects to be saved.
file	The filename (character) of the file in which the dataset will be located. It is also possible to provide an object of class H5IdComponent representing a H5 location identifier (file or group). See H5Fcreate(), H5Fopen(), H5Gcreate(), H5Gopen() to create an object of this kind.
name	A character vector of names for the datasets. The length of the name vector should match the number of objects.
createnewfile	If TRUE, a new file will be created if necessary.
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. Using native = TRUE increases HDF5 file portability between programming languages. A file written with native = TRUE should also be read with native = TRUE

Details

The objects will be saved to the HDF5 file. If the file does not exists it will be created. The data can be read again by either h5dump() or individually for each dataset by h5read().

Value

Nothing returned.
