h5save {rhdf5} | R Documentation

## Saves a series of 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. For advanced programmers it is 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.
