Release 2.0.1
=============

New features
------------

:mod:`rpy2.robjects`:

- Property `names` for the :class:`RVector` methods :meth:`getnames` 
  and :meth:`setnames` (this was likely forgotten for Release 2.0.0).

- Property `rclass` for :class:`RObjectMixin` 

Changes
-------

:mod:`rpy2.robjects`:

- :meth:`rclass` becomes :meth:`getrclass`

Bugs fixed
----------

- Having the environment variable R_HOME specified resulted in an error
  when importing :mod:`rpy2.rinterface` # root of the problem spotted by Peter

- Setup.py has no longer a (possibly outdated) static hardcoded version number
  for rpy2

- Testing no longer stops with an error in the absence of the third-party
  module :mod:`numpy`

- :meth:`rpy2.rlike.container.TaggedList.pop` is now returning the element
  matching the given index



Release 2.0.0
=============

New features
------------

- New module :mod:`rpy2.robjects.conversion`.

- New module :mod:`rpy2.robjects.numpy2ri` to convert :mod:`numpy` objects
  into :mod:`rpy2` objects. 
  # adapted from a patch contributed by Nathaniel Smith


Changes
-------

- :meth:`RObject.__repr__` moved to :meth:`RObject.r_repr`


Bugs fixed
----------

- Informative message returned as RuntimeError when failing to find R's HOME

- Use the registry to find the R's HOME on win32
  # snatched from Peter's earlier contribution to rpy-1.x


Release 2.0.0rc1
================

:mod:`rpy2.rpy_classic`:

- :meth:`rpy_classic.RObj.getSexp` moved to a 
  property :attr:`rpy_classic.Robj.sexp`.

:mod:`rpy2.robjects`:

- :meth:`RObject.__repr__` moved to :meth:`RObject.r_repr`

- :meth:`ri2py`, :meth:`ro2py`, and :meth:`py2ri` moved to the new module
  :mod:`conversion`. Adding the prefix `conversion.` to calls
  to those functions will be enough to update existing code


Bugs fixed
----------

- Informative message returned as RuntimeError when failing to find R's HOME

- Use the registry to find the R's HOME on win32
  # snatched from Peter's earlier contribution to rpy-1.x


Release 2.0.0rc1
================

New features
------------

- added :data:`__version__` to rpy2/__init__.py

:mod:`rpy2.robjects`:

- added classes :class:`StrVector`, :class:`IntVector`, :class:`FloatVector`, :class:`BoolVector`

:mod:`rpy2.rinterface`:

- added missing class :class:`BoolSexpVector`.


Changes
-------

:mod:`rpy2.robjects`:

- does not alias :class:`rinterface.StrSexpVector`, :class:`rinterface.IntSexpVector`, :class:`rinterface.FloatSexpVector` anymore

- Constructor for :class:`rpy2.robjects.RDataFrame` checks that R lists are data.frames (not all lists are data.frame)

- Formerly new attribute :attr:`_dotter` for :class:`R` is now gone. The documentaion now points to :mod:`rpy2.rpy_classic` for this sort of things.

Bugs fixed
----------

- conditional typedef in rinterface.c to compile under win32 # reported and initial proposed fix from Paul Harrington

- __pow__ was missing from the delegator object for robjects.RVector (while the documentation was claiming it was there) # bug report by Robert Nuske

- Earlier change from Sexp.typeof() to getter Sexp.typeof was not reflected in :mod:`rpy2.rpy_classic` # bug report by Robert Denham

 
Release 2.0.0b1
===============

New features
------------

:mod:`rpy2.robjects`:

- added :meth:`setenvironment` for :class:`RFormula`, and defined `environment` as a property

- defined `names` as a property for :class:`RVector`

:mod:`rpy2.rinterface`:

- added functions :func:`get_initoptions` and :func:`set_initoptions`.

- new attribute :attr:`_dotter` for :class:`R` singleton. Setting it to True will translate '_' into '.' if the attribute is not found 

Changes
-------

- constructor for RDataFrame now now accepts either :class:`rlike.container.TaggedList` or :class:`rinterface.SexpVector`

:mod:`rpy2.rinterface`:

- :func:`sexpTypeEmbeddedR` is now called :func:`str_typeint`.

- :attr:`initOptions` is now called :attr:`initoptions`. Changes of options can only be done through :func:`set_initoptions`.


Bugs fixed
----------

- crash of :meth:`Sexp.enclos` when R not yet initialized (bug report #2078176)

- potential crash of :meth:`Sexp.frame` when R not yet initialized

- proper reference counting when handling, and deleting, :attr:`Sexp.__sexp__` generated CObjects

- setup.py: get properly the include directories (no matter where they are) #bug report and fix adapted from Robert Nuske

- setup.py: link to external lapack or blas library when relevant

- added a MANIFEST.in ensuring that headers get included in the source distribution #missing headers reported by Nicholas Lewin-Koh

- :func:`rinterface.str_typeint` was causing segfault when called with 99

- fixed subsetting for LANGSXP objects


Release 2.0.0a3
===============

New features
------------

:mod:`rpy2.rinterface`:

- :func:`setReadConsole`: specify Python callback for console input

- `R` string vectors can now be built from Python unicode objects

- getter :attr:`__sexp__` to return an opaque C pointer to the underlying R object

- method :meth:`rsame` to test if the underlying R objects for two :class:`Sexp` are the same.

- added `emptyEnv` (R's C-level `R_EmptyEnv`)

- added method :meth:`Sexp.do_slot_assign`

:mod:`rpy2.robjects`:

- R string vectors can now be built from Python unicode objects

:mod:`rpy2.rlike`:

- module :mod:`functional` with the functions :func:`tapply`, :func:`listify`, :func:`iterify`.

- module :mod:`indexing` with the function :func:`order`

- method :meth:`TaggedList.sort` now implemented

 
Changes
-------

:mod:`rpy2.rinterface`:

- :func:`initEmbeddedR` is only initializing if R is not started (no effect otherwise, and no exception thrown anymore)

- the method :meth:`Sexp.typeof` was replaced by a Python `getter` :attr:`typeof`.

- the method :meth:`Sexp.named` was replaced by a Python `getter` :attr:`named`.

- R objects of type LANGSXP are now one kind of vector (... but this may change again)

- R objects of type EXPRSXP are now handled as vectors (... but this may change again)

- :func:`initEmbeddedR` renamed to :func:`initr`

- :func:`endEmbeddedR` renamed to :func:`endr`


:mod:`rpy2.robjects`:

- :class:`R` remains a singleton, but does not throw an exception when multiple instances are requested


Bugs fixed
----------

- unable to compile on Python2.4 (definition of aliases to Python2.5-specific were not where they should be).

- overflow issues on Python 2.4/64 bits when indexing R vector with very large integers.

- handling of negative indexes for :class:`SexpVector`'s :meth:`__getitem__` and :meth:`__setitem__` was missing

- trying to create an instance of :class:`SexpVector` before initializing R raises a RuntimeException (used to segfault)

- experimental method :meth:`enclos` was not properly exported

- setup.py was exiting prematurely when R was compiled against an existing BLAS library

- complex vectors should now be handled properly by :mod:`rpy2.rinterface.robjects`.

- methods :meth:`rownames` and :meth:`colnames` for :class:`RDataFrame` were incorrect.

Release 2.0.0a2

- experimental methods :meth:`frame` and :meth:`enclos` for SexpEnvironment corresponding to R's C-level FRAME and ENCLOS

- method :meth:`rcall` for :class:`ClosureSexp`

- new experimental class :class:`SexpLang` for R language objects.


Bugs fixed
----------

- R stack checking is disabled (no longer crashes when multithreading)

- new class :class:`RFormula`

- new helper class :class:`RVectorDelegator` (see below)

- indexing RVector the "R way" with subset is now possible through a delegating attribute (e.g., myvec.r[True] rather than myvec.subset(True)). #suggested by Michael Sorich

- new class :class:`RDataFrame`. The constructor :meth:`__init__` is still experimental (need for an ordered dictionnary, that will be in before the beta

- filled documentation about mapping between objects

Changes
-------

- many fixes and additions to the documentation

- improved GTK console in the demos

- changed the major version number to 2 in order to avoid confusion with rpy 1.x # Suggested by Peter and Gregory Warnes

- moved test.py to demos/example01.py
