Rpy

=============

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

- Crash with R-3.0.2. Changes in R-3.0.2's C API coupled to a strange behaviour
with R promises caused the problem. (PR 150)

=============

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

- ggplot2's "guides" were missing

- ggplot2's "theme_classic" was missing (PR 143)

- ggplot2's "element_rect" was missing (PR 144)

- :func:`rpy2.interactive.packages` was broken (PR 142)

=============

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

- Several reports of segfault on OS X (since rpy2-2.3.1 - PR 109)

- More fixes in converting `DataFrames` with dates from `pandas`

============

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

- Missing mapping to ggplot2's `scale_shape_discrete` function

- Better handling of dates in Pandas

- Constructor for POSIXct improved (and fixed)

Changes
-------

- The attribute :attr:`rclass` is no longer read-only and can be set
(since R allows it)

- Importing the module :mod:`rpy2.interactive` no longer activates
event processing by default (triggering concurrency errors
when used with ipython).

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

- New module :mod:`rpy2.interactive.ipython` (so far plotting
automatically a ggplot2 figure in the iPython's console)

- It is now possible to set the :attr:`rclass`.

============

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

- Spurious error when running unit tests with Python 3 and numpy
installed

- Missing mapping to ggplot2's `geom_dotplot` function

- Warnings are not longer printed (see Changes below)

Changes
-------

- Bumped target version of ggplot2 to 0.9.3.1

- Warnings are not longer printed. The C-level function in R became
hidden in R-3.0, and the cost of an R-level check/print is relatively
high if the R code called is very short. This might evolve into
printing warnings only if interactive mode in Python (if this can
be checked reliably).

=============

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

- Some of the data.frames converted from :mod:`pandas` were triggering
a :class:`TypeError` when calling :func:`repr`

- In :mod:`rpy2.robjects.lib.ggplot2`, a mapping to `coord_fixed` was
missing (PR 120)

- Using the parameter `lib_loc` in a call to
:func:`rpy2.robjects.packages.importr` was resulting in an error (PR 119)

- Creating a `layer` through the `rpy2.robjects.lib.ggplot2` interface did
not accept parameters (PR 122)

- Testing the Python version was crashing of a number of unsupported Python
versions (<= 2.6) (PR 117)

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

- New module pandas2ri to convert from mod:`pandas` `DataFrame` objects

- New classes :class:`rpy2.robjects.lib.grid.Unit` and
:class:`rpy2.robjects.lib.grid.Gpar` to model their counterparts in
R's `grid` package as they were previously missing from rpy2.
