Changes in rpy2
Release 2.0.1
New features
rpy2.robjects:
- Property names for the RVector methods getnames()
and setnames() (this was likely forgotten for Release 2.0.0).
- Property rclass for RObjectMixin
Bugs fixed
- Having the environment variable R_HOME specified resulted in an error
when importing 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- Setup.py has no longer a (possibly outdated) static hardcoded version number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 numpy
- rpy2.rlike.container.TaggedList.pop() is now returning the element
matching the given index
Release 2.0.0
New features
- New module rpy2.robjects.conversion.
- New module rpy2.robjects.numpy2ri to convert numpy objects
into rpy2 objects.
# adapted from a patch contributed by Nathaniel Smith
Changes
- RObject.__repr__() moved to 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
rpy2.rpy_classic:
- rpy_classic.RObj.getSexp() moved to a
property rpy_classic.Robj.sexp.
rpy2.robjects:
- RObject.__repr__() moved to RObject.r_repr()
- ri2py(), ro2py(), and py2ri() moved to the new module
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 __version__ to rpy2/__init__.py
rpy2.robjects:
- added classes StrVector, IntVector, FloatVector, BoolVector
rpy2.rinterface:
- added missing class BoolSexpVector.
Changes
rpy2.robjects:
- does not alias rinterface.StrSexpVector, rinterface.IntSexpVector, rinterface.FloatSexpVector anymore
- Constructor for rpy2.robjects.RDataFrame checks that R lists are data.frames (not all lists are data.frame)
- Formerly new attribute _dotter for R is now gone. The documentaion now points to 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 rpy2.rpy_classic # bug report by Robert Denham
Release 2.0.0b1
New features
rpy2.robjects:
- added setenvironment() for RFormula, and defined environment as a property
- defined names as a property for RVector
rpy2.rinterface:
- added functions get_initoptions() and set_initoptions().
- new attribute _dotter for R singleton. Setting it to True will translate ‘_’ into ‘.’ if the attribute is not found
Changes
rpy2.robjects:
- constructor for RDataFrame now now accepts either rlike.container.TaggedList or rinterface.SexpVector
rpy2.rinterface:
- sexpTypeEmbeddedR() is now called str_typeint().
- initOptions is now called initoptions. Changes of options can only be done through set_initoptions().
Bugs fixed
- crash of Sexp.enclos() when R not yet initialized (bug report #2078176)
- potential crash of Sexp.frame() when R not yet initialized
- proper reference counting when handling, and deleting, 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
- rinterface.str_typeint() was causing segfault when called with 99
- fixed subsetting for LANGSXP objects
Release 2.0.0a3
New features
rpy2.rinterface:
- setReadConsole(): specify Python callback for console input
- R string vectors can now be built from Python unicode objects
- getter __sexp__ to return an opaque C pointer to the underlying R object
- method rsame() to test if the underlying R objects for two Sexp are the same.
- added emptyEnv (R’s C-level R_EmptyEnv)
- added method Sexp.do_slot_assign()
rpy2.robjects:
- R string vectors can now be built from Python unicode objects
rpy2.rlike:
- module functional with the functions tapply(), listify(), iterify().
- module indexing with the function order()
- method TaggedList.sort() now implemented
Changes
rpy2.rinterface:
- initEmbeddedR() is only initializing if R is not started (no effect otherwise, and no exception thrown anymore)
- the method Sexp.typeof() was replaced by a Python getter typeof.
- the method Sexp.named() was replaced by a Python getter 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)
- initEmbeddedR() renamed to initr()
- endEmbeddedR() renamed to endr()
rpy2.robjects:
- 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 SexpVector‘s __getitem__() and __setitem__() was missing
- trying to create an instance of SexpVector before initializing R raises a RuntimeException (used to segfault)
- experimental method 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 rpy2.rinterface.robjects.
- methods rownames() and colnames() for RDataFrame were incorrect.
Release 2.0.0a2
New features
rpy2.rlike:
rpy2.rinterface:
- method named(), corresponding to R’s C-level NAMED
- experimental methods frame() and enclos() for SexpEnvironment corresponding to R’s C-level FRAME and ENCLOS
- method rcall() for ClosureSexp
- new experimental class SexpLang for R language objects.
Bugs fixed
- R stack checking is disabled (no longer crashes when multithreading)
- fixed missing R_PreserveObject for vectors (causing R part of the object to sometimes vanish during garbage collection)
- prevents calling an R function when R has been ended (raise RuntimeException).
Release 2.0.0a1
New features
rpy2.robjects:
- method getnames() for RVector
- experimental methods __setitem__() and setnames() for RVector
- method ‘getnames’ for RArray
- new class RFormula
- new helper 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 RDataFrame. The constructor __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
rpy2.robjects:
- changed method name getNames to getnames where available (all lower-case names for methods seems to be the accepted norm in Python).
Bugs fixed
rpy2.robjects:
- fixed string representation of R object on Microsoft Windows (using fifo, not available on win32)
- __getattr__() for RS4 is now using ri2py()
rpy2.rinterface:
- fixed context of evaluation for R functions (now R_GlobalEnv)
