Changes in version 2.24.0:
NEW FEATURES
o Removed bundled HDF5 library - rhdf5 now depends on Rhdf5lib. This
updates the version of HDF5 to 1.8.19.
o Functions H5Ldelete() and h5delete() added to provide mechanisms for
removing items from HDF files.
o Added argument `native` to many functions, which allows data to be
treated as row-major rather than column-major, improving
portability with other programming languages.
o Added function H5Sunlimited() allowing creation of extensible
datasets - thanks to Brad Friedman
BUG FIXES
o Datasets can now be subset using `[` and a range of values e.g.
did[,1:5].
o Writing a data.frame that contains factors and setting
DataFrameAsCompound=FALSE now works.
o Many functions that would leave open file handles after exiting
under error conditions have been fixed.
o Performance improvements in h5read().
Changes in version 2.20.0:
NEW FEATURES
o Indexing into spaces with more than .Machine$integer.max elements is
supported using numeric (rather than integer) indexing; this
provides exact indexing into spaces with about 51 bits of
precision.
o Zero-length indexing is now supported (returning zero-length slabs).
BUG FIXES
o Using bit64conversion = "double" would always warn about loss of
precision, but now only warns when precision is actually lost.
Changes in version 2.18.0:
NEW FEATURES
o The low-level functions H5Pset_libver_bounds and
H5Pget_libver_bounds is implemented. Creating files that can only
be read by library versions 1.8 or later allows the usage of large
attributes and improves performance.
USER VISIBLE CHANGES
o Per default all HDF5 files will be created with version 1.8 as lower
bound. That means the created files can only be read with HDF5
library versions >= 1.8. This changes allows the usage of large
attributes and leads to performance improvements. If one wants to
create a file that is readable with the earliest version of HDF5,
one has to call H5Fcreate with fapl=h5default("H5P").
o Warning messages from the package C code can now be suppressed by
the R-function suppressWarnings().
Changes in version 2.16.0:
NEW FEATURES
o New access of HDF5 files by file, group and dataset handles. HDF5
groups and datasets can be read and written by the $-operator (e.g.
h5f$A) and the [-operator can be used for partial reading and
writing of datasets (e.g. h5d[3,,]).
o New low level general library function H5Dget_create_plist
implemented.
o Removed #include <R.H> from external C code. To be compatible with
newest C-compilers and current R-devel
Changes in version 2.14.0:
NEW FEATURES
o improved handling of error messages: HDF5 error messages are
simplified and forwarded to R.
o When reading integer valued data, especially 64-integers and
unsigned 32-bit integers, overflow values are now replaced by NA's
and a warning is thrown in this case.
o When coercing HDF5-integers to R-double, a warning is displayed when
integer precision is lost.
o New low level general library function H5Dget_storage_size
implemented.
BUG FIXES
o Memory allocation on heap instead of stack for reading large
datasets (Thanks to a patch from Jimmy Jia).
o Some bugs have been fixed for reading large 64-bit integers and
unsigned 32-bit integers.
o A bug was fixed for reading HDF5 files containing soft links.
Changes in version 2.12.0:
NEW FEATURES
o Filenames are expanded with normalizePaths.
o New function h5set_extent implemented.
o New low level function H5Sset_extent_simple implemented.
BUG FIXES
o Segmentation fault while writing data type names for uncommitted
data types.
Changes in version 2.10.0:
NEW FEATURES
o Added support for HDF5 property lists.
o Added property list arguments to H5Dcreate and H5Dopen.
o New function h5readAttributes implemented that reads all HDF5
attributes of one object.
o New function h5version implemented.
o fillValue parameter added to h5createDataset.
o New low level general library functions H5Lcreate_external,
H5Fis_hdf5, H5Fget_filesize, H5Fget_name, H5Pcreate, H5Pcopy,
H5Pget_class, H5Pclose, H5Pclose_class, H5Pset_char_encoding,
H5Pset_create_intermediate_group, H5Pset_chunk_cache,
H5Pset_layout, H5Pset_chunk, H5Pget_chunk, H5Pset_deflate,
H5Pset_fill_value, H5Pset_fill_time, H5Pset_alloc_time, H5Pequal
implemented.
o Support for parallel Make (make -j)
USER VISIBLE CHANGES
o A warning is shown in high level function (h5read, h5write and
others), if an open HDF5 handle already exists for the specified
filename.
BUG FIXES
o Error in h5write for 0-length objects, as a consequence of automatic
determining chunk size
o missing size parameter message in h5createDataset now correctly
display
o checking for open file identifiers in h5read and h5ls now only
searches for file names in open files, groups and datasets.
o assignment has now correct pointer target type (void *) in
H5Pset_fill_value
Changes in version 2.8.0:
NEW FEATURES
o New function h5version implemented.
o New low level general library functions H5open, H5close,
H5garbage_collect, H5get_libversion, and H5Dset_extent implemented.
USER VISIBLE CHANGES
o h5createDataset automatically uses chunking and compression.
o Added a warning if chunk size is equal to dimensions for large
compressed datasets.
BUG FIXES
o C-stack overflow when reading large fixed-length strings.
o error in i/o with chunksize or blocksize parameters.
o compiling errors due to missing int return value.
Changes in version 2.6.0:
NEW FEATURES
o support for logical added
o support for reading attributes added (use read.attributes=TRUE)
o enabeled compression for data.frame in h5write
USER VISIBLE CHANGES
o Use BiocStyles for package vignette
Changes in version 2.4.0:
NEW FEATURES
o support for reading 64-bit integers added
o support for reading variable length strings added
o support for reading scalar objects added
USER VISIBLE CHANGES
o NEWS.Rd added
o display of chunksize.pdf as a vignette avoided
