Hello everyone, I try without success to install the package rPython I get the message ----------------------------------------------------------------------- * installing *source* package ‘rPython’ ... could not locate python-config ERROR: configuration failed for package ‘rPython’ * removing ‘/home/armel/R/x86_64-pc-linux-gnu-library/2.14/rPython’ The downloaded...

Hola, ¿qué tal? Estoy buscando "alpha testers" para mi paquete rPython. El paquete es la evolución natural de rJython, un paquete de R que permite llamar a Jython, el dialecto de Python que corre sobre la máquina virtual de Java, desde R. rPython permite llamar al verdadero Python. Funciona perfectamente en mi máquina, pero necesito ver qué problemas de instalación y...

rPython appears to provide an interface from R to Python by embedding Python and I'd think that it can safely assume that R has been initialized, but might not be the point here. The issue is that a Python package embedding itself R (here rpy2) appears to have no way to know that earlier in the life o...

...tion that with an API elegance and convenience might sometimes be superior to necessity, the suggested pattern ("every program, including R itself, keeping its own flag") does no work too well when the nested embedding of R is involved. A concrete example is: ``` $ R -q > library('rPython'); python.exec('import rpy2.robjects') R is already initialized ``` https://bitbucket.org/rpy2/rpy2/issue/278/r-in-python-via-rpy2-in-r-via-rpython#comment-17843761 2015-05-03 18:12 GMT-04:00 Duncan Murdoch <murdoch.duncan at gmail.com>: > On 03/05/2015 4:34 PM, Laurent Gaut...

First test of Rpython to LLVM JIT.  Test results show Rpython-to-LLVM is 4x faster than PyPy, 200x faster than Python2, and 260x faster than Python3. http://pyppet.blogspot.com/2012/04/rpython-to-llvm.html Thanks to Mahadevan for making PyLLVM, and the PyPy team for making Rpython. -brett- -------------- next part ---...

Hi, I've been trying to work with the RPython interface and noticed a strange problem. When stdin is not a terminal the R part of the RPython interface complains. EG, $ python RPython.py Initialized R-Python interface package. works fine, but $ python < RPython.py This particular strangeness isn't a problem in this context,...

Hola. Me gustaría saber si alguno de ustedes sabe cómo llamar una función de python desde R. Antes usaba felizmente rpython pero desde la última versión de R he tenido este mensaje > install.packages("rPython", repos="http://R-Forge.R-project.org") Installing package(s) into ‘/home/vate01/R/x86_64-unknown-linux-gnu-library/2.15’ (as ‘lib’ is unspecified) Mensajes de aviso perdidos package ‘rPytho...

When the package is loaded by "library('rPython')", R is obviously initialized. You don't need to query it to ask th...

Hi, I currently write a LLVM backend for RPython, a programming language and toolchain to write dynamic language interpreters. For example, this toolchain powers PyPy, a fast Python interpreter. In the moment the implementation uses a shadowstack to manage garbage collection stack roots. To improve performance, I experimented with LLVM's gar...

A question for a (experienced) user of the RPython package on linux. I'm trying to call R from python on a linux (Suse 7.3) box. After installing R CMD INSTALL -c RSPython_0.5-2.tar.gz I start python and do: >>> import sys >>> sys.path.append('/usr/local/lib/R/library/RSPython') >>> sys.path.append('/...

Hi, There appear to be no way to check whether R has already been initialized. Could a function like "Rf_isinitialized" be added to the API ? Best, Laurent [[alternative HTML version deleted]]

...years of research, engineering, management and sprinting efforts, concluding the 28 months phase of EU co-funding! Although still not mature enough for general use, PyPy 1.0 materializes for the first time the full extent of our original vision: - A flexible Python interpreter, written in "RPython": - Mostly unaware of threading, memory and lower-level target platform aspects. - Showcasing advanced interpreter features and prototypes. - Passing core CPython regression tests, translatable to C, LLVM and .NET. - An advanced framework to translate such interpreters and programs...
