Interface to the HDF5 Library
Description
hdf5save and hd5fload provide an experimental interface
to version 5 of the NCSA HDF library. hdf5save writes a
representation of R objects to the specified file in a form which
can be read by software which understands the HDF5 format.
The objects can be read back from the file at a later
date by using the function hdf5load.
Not all R types are supported and it probably doesn't make sense to put some of them into an HDF file (e.g. closures). However, lists, strings, vectors, and matrices work. Lists map to HDF groups. Vectors and matrices map to datasets.
This capability is only available on machines which have the HDF5 library, version 1.2 or higher (freely available from the reference below).
Usage
hdf5save(file, ...)
hdf5load(file, load=TRUE)
Arguments
file |
the name of the file in which the objects will be stored. |
... |
the names of the objects to be saved. |
load |
a logical value. If |

Examples
## Not run:
(m <- cbind(A = 1, diag(4)))
ll <- list(a=1:10, b=letters[1:8]);
l2 <- list(C="c", l=ll); PP <- pi
hdf5save("ex1.hdf", m, PP, ll, l2)
rm(m,PP,ll,l2) # and reload them:
hdf5load("ex1.hdf")
m # read from "ex1.hdf"; buglet: dimnames dropped
str(ll) # buglet: "pairlist" instead of "list"
str(l2)
## End(Not run)
