Hi,
rpy2-2.9.0 is finally released. The interface to R and Python's respective
ecosystems was upgraded. If using the Docker image, note that the content
of the former image was sliced into 3 images to allow having a smaller base
image. The 3 images are: rpy2/rpy2 (base), rpy2/jupyter, rpy2/polyglot.
User-visible changes are:
Release 2.9.0
=============
New features
------------
- New module :mod:`rpy2.situation` to extract and report informations
about the environment, such as where is the R HOME, what is the
version of R, what is the version of R rpy2 was built with, etc...
The module is also designed to be run directly and provide diagnostics:
`python -m rpy2.situation`.
- :meth:`Environment.values`, :meth:`Environment.pop`,
:meth:`Environment.popitems`, :meth:`Environment.clear`
to match :meth:`dict.values`,
:meth:`dict.pop`, :meth:`dict.popitems`, :meth:`dict.clear`.
- :class:`VectorOperationsDelegator` now has a method `__matmul__` to
implement
Python's matrix multiplication operator (PEP-0645).
- A rule to convert R POSIXct vectors to pandas Timestamp vectors was added
(issue #418).
- method :meth:`_repr_html_` for R vectors to display HTML in jupyter.
Changes
-------
- Starting several times the singleton :class:`EventProcessor` longer
results
in a :class:`RuntimeError`. This is now only a warning, addressing
issue #182.
- The target version for the R package `dplyr` mapped is now 0.7.1, and
:func:`rpy2.robjects.lib.dplyr.src_dt` (issue #357) and
:func:`rpy2.robjects.lib.dplyr.src_desc` are no longer present.
- :meth:`Environment.keys` is now a iterator to match :meth:`dict.keys`,
also an interator in Python 3.
- Target version of `ggplot2` library is 2.2.1.
- Option `stringsasfactors` in the constructor for the class `DataFrame`.
If `False`, the
strings are no longer converted to factors. When converting from pandas
data frames
the default is to no longer convert columns of strings to factors.
- The R "magic" for jupyter is now more consistently using the conversion
system, and the
use of custom converters through the magic argument `-c` will work as
expected.
- Docker-related files moved to directory docker/ (where variants image for
rpy2 are available)
Bugs fixed
----------
- :func:`numpy.float128` is not available on all platforms. The unit test
for it is now skipped on systems where it is not present (issue #347)
- R pairlist objects can now be sliced (and issue #380 is resolved).
- Passing parameters names that are empty string to R function was
causing a segfault (issue #409).
- Trying to build an atomic R vector from a Python object that has a length,
but it not a sequence nor an iterator was causing a segfault (issue #407).
