PyEphem provides scientific-grade astronomical computations for the Python
programming language. Given a date and location on the Earth's surface, it can
compute the positions of the Sun and Moon, of the planets and their moons, and
of any asteroids, comets, or earth satellites whose orbital elements the user
can provide. Additional functions are provided to compute the angular
separation between two objects in the sky, to determine the constellation in
which an object lies, and to find the times at which an object rises, transits,
and sets on a particular day.

Release 2.3.0
=============
New Features
------------
:mod:`rpy2.rinterface`:
- C-level API, allowing other C-level modules to make use of utilities
without going through the Python level. The exact definition of
the API is not yet fixed. For now there is
PyRinteractive_IsInitialized() to assess whether R was initialized
(through :mod:`rpy2.rinterface` or not).
- C-module _rpy_device, allowing one to implement R graphical devices
in Python [(very) experimental]
- Tracking of R objects kept protected from garbage collection by rpy2
is now possible.
- New method :meth:`Sexp.rid` to return the identifier of the R object
represented by a Python/rpy2 object
:mod:`rpy2.rinteractive`:
- Dynamic build of Python docstrings out of the R manual pages
:mod:`rpy2.robjects.help`:
- Build dynamic help
:mod:`rpy2.robjects.packages:
- Build anonymous R packages from strings
- When using :func:`importr`, the datasets are added as an attribute
:attr:`data`, itself an instance of a new class :class:`PackageData`.
It no longer possible to access datasets are regular objects from
a code package (because of changes in R), and the new system is
more robust against quirks.
Changes
-------
:mod:`rpy2.rinterface`:
- :attr:`SexpClosure.env` to replace the method `closureenv`.
Release 2.2.6
=============
Bugs fixed
----------
- Newest R-2.15 and ggplot2 0.9 broke the ggplot2 interaface
in :mod:`rpy2.robjects.lib.ggplot2`
Release 2.2.5
=============
Bugs fixed
----------
- install process: Library location for some of the R installations
- should compile on win32 (thanks to a patch from Evgeny Cherkashin),
a work to a limited extend
Release 2.2.4
=============
Bugs fixed
----------
- Memory leak when creating R vectors from Python (issue #82)
Release 2.2.3
=============
Bugs fixed
----------
- Dynamic construction of S4 classes was looking for R help as 'class.<class>'
rather than '<class>-class'
- The cleanup of temporary directories created by R was not happening if
the Python process terminated without calline :func:`rpy2.rinterface.endr()`
(issue #68, and proof-of-principle fix by chrish42)
Release 2.2.2
=============
Bugs fixed
----------
- With the robjects layer, repr() on a list containing non-vector elements
was failing
Release 2.2.1
=============
Bugs fixed
----------
- MANIFEST.in was missing from MANIFEST.in, required with Python 3
Release 2.2.0
=============
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
compiling rpy2 (ported to release 2.1.6)
- Long-standing issue with readline fixed (issue #10)
Release 2.1.9
=============
Bugs fixed
----------
- The R class in rpy2.robjects is now truly a singleton
- When using numpy 1.5 and Python >= 2.7, the exposed buffer for R numerical (double)
vectors or arrays was wrong.
Release 2.1.8
=============
Bugs fixed
----------
- Fixed issue with R arrays with more than 2 dimensions and numpy arrays
(issue #47 - backported from the branch 2.2.x).
Release 2.1.7
=============
Bugs fixed
----------
- More fixes for the automated detection of include and libraries at build time.
Release 2.1.6
=============
Bugs fixed
----------
- Further fixes in the automatic detection of includes and libraries
needed to compile rpy2 against R. The detection code has
been refactored (backport from the 2.2.x branch)
Release 2.1.5
=============
Bugs fixed
----------
- fixes the automatic detection of R_HOME/lib during building/compiling
when R_HOME/lib is not in lib/ (issue #54)
Release 2.1.4
=============
New features
------------
- :mod:`rpy2.robjects.lib.ggplot2` now has the functions :func:`limits`,
:func:`xlim`, :func:`ylim` exposed (patch contributed anonymously)
Bugs fixed
----------
- Install script when the BLAS library used by R is specified as a library
file (patch by Michael Kuhn)

Ipopt (Interior Point OPTimizer, pronounced eye-pea-Opt)
is a software package for large-scale nonlinear optimization.
It is designed to find (local) solutions of mathematical
optimization problems of the form
min_{x in R^n} f(x)
s.t. g_L <= g(x) <= g_U
x_L <= x <= x_U
where f(x): R^n --> R is the objective function,
and g(x): R^n --> R^m are the constraint functions.
The vectors g_L and g_U denote the lower and upper bounds on the
constraints, and the vectors x_L and x_U are the bounds on the
variables x. The functions f(x) and g(x) can be nonlinear and
nonconvex, but should be twice continuously differentiable.
Note that equality constraints can be formulated in the above
formulation by setting the corresponding components of g_L and
g_U to the same value.
Ipopt is part of the COIN-OR Initiative.

SciPy 0.12.1 is a bug-fix release with no new features compared to
0.12.0. The single issue fixed by this release is a security issue in
``scipy.weave``, which was previously using temporary directories in
an insecure manner under certain circumstances.
