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.
- 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`.
- The target version for the R package `dplyr` mapped is now 0.7.1, and
:func:`rpy2.robjects.lib.dplyr.src_dt` 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
- R pairlist objects can now be sliced.
- Passing parameters names that are empty string to R function was
causing a segfault.
- 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
