=============
New Features
------------
- Support for Python 3, and for some of its features ported to Python 2.7
:mod:`rpy2.robjects`:
- :meth:`Environment.keys` to list the keys
- classes :class:`robjects.vectors.POSIXlt` and
:class:`robjects.vectors.POSIXlt` to represent vectors of R
dates/time
- :func:`packages.get_packagepath` to get the path to an R package
- module :mod:`rpy2.robjects.help` to expose the R help system to Python
- Metaclass utilities in :mod:`rpy2.robjects.methods`, allowing to reflect
automatically R S4 classes as Python classes.
- :meth:`rpy2.robjects.vectors.FactorVector.iter_labels` to iterate over the labels
- :class:`rpy2.robjects.vectors.ListVector` to represent R lists.
- Constructor for :class:`rpy2.robjects.vectors.ListVector` and
:class:`rpy2.robjects.vectors.DataFrame` accept any iterable at the condition
that the elements iterated through also valid subscripts for it (e.g., given
an iterable v, the following is valid:
.. code-block:: python
x[k] for x in v
:mod:`rpy2.rinterface`:
- :data:`NA_Complex` and :class:`NAComplexType` for missing complex values.
- :class:`SexpExtPtr` to represent R objects of type EXTPTR (external pointers).
- :func:`rpy2.rinterface.parse` to parse a string a R code
- :func:`rpy2.rinterface.rternalise` to wrap Python function as :class:`SexpClosure` that can
be called by R just as it was a function of its own.
- :class:`rpy2.rinterface.RNULLType` for R's C-level NULL value and
:class:`rpy2.rinterface.UnboundValueType` for R's C-level R_UnboundValue
(both singletons).
- :meth:`rinterface.SexpVector.index`, of similar behaviour to :meth:`list.index`.
- :meth:`rpy2.rinterface.Sexp.list_attrs` to list the names of all R attributes
for a given object.
- :class:`rpy2.rinterface.ByteSexpVector` to represent R 'raw' vectors.
- constant `R_LEN_T_MAX` to store what is the maximum length for a vector in R.
- tuple `R_VERSION_BUILD` to store the version of R rpy2 was built against
- getter :attr:`Sexp.rclass` to return the R class associated with an object
:mod:`rpy2.rlike`:
- :class:`container.OrdDict` get proper methods :meth:`keys` and `get`
:mod:`rpy2.interactive`:
- A new sub-package to provide utilities for interactive work, either for
handling R interactive events or use Python for interactive programming
(as often done with the R console)
Changes
-------
:mod:`rpy2.robjects`:
- NA_bool, NA_real, NA_integer, NA_character and NA_complex are now
deprecated (and removed).
NA_Logical, NA_Real, NA_Integer, NA_Character, NA_Complex should be used.
- :class:`rpy2.robjects.packages.Package` now inherits from :class:`types.ModuleType`
- classes representing R vector also inherit their type-specific
rinterface-level counterpart.
- Importing the :class:`rpy2.robjects.numpy2ri` is no longer sufficient
to active the conversion. Explicit activation is now needed; the function
`activate` can do that.
:mod:`rpy2.rinterface`:
- :class:`IntSexpVector`, :class:`FloatSexpVector`,
:class:`StrSexpVector`, :class:`BoolSexpVector`, :class:`ComplexSexpVector`
are now defined at the C level, improving performances
and memory footprint whenever a lot of instances are created.
Bugs fixed
----------
- Better and more explicit detection system for needed libraries when
