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 packages are in

Dear R People: I have been experimenting with rPython, rSymPy, and rJython. Here is my latest snag: > library(rJython) Loading required package: rJava Loading required package: rjson > library(rSymPy) > rJython <- rJython() > x <- "x" > y <- "y" > rJython$exec("from sympy import *") Error in .jcall("RJavaTools",

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 -------------- An HTML attachment was scrubbed...

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, but it does become a problem when I try to use the

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 of the process R was initialized. 2015-05-03 19:48 GMT-04:00 Duncan Murdoch

Beside the possible argumentation 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

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

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('/usr/local/lib/R/library/RSPython/Python')

Por favor, estoy aprendiendo R para aplicarlo exclusivamente en modelos jerárquicos lineales o multinivel. Todo lo que me puedan ayudar les quedaré muy agradecido. Cordialmente, Jairo [[alternative HTML version deleted]]

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]]

Muchísimas gracias Eric, lo del rebote debe ser porque en la escuela cambiaron el dominio y debes estar mandando el mensaje al la dirección vieja 'npolanco@*cuij*.edu.cu', como cambiaron el dominio *CUIJ* por *UIJ* ahora la dirección es 'npolanco@*uij*.edu.cu' que es como me registre a la lista recientemente, como no sabia cambiar el correo en el usuario y le envié un mensaje

Hi, I'm trying to install RSPython v0.5-4 on a debian machine (woody, testing) but am having the following problem. $R CMD INSTALL -c --library=/usr/lib/R/library RSPython_0.5-4.tar.gz 2>err But then... $python >> import RS Error in .PythonInit() : Error in Python call: values Error in library("RSPython") : .First.lib failed for 'RSPython' Traceback (most recent

Hola a todos: Las versiones oficiales de R no son versiones beta, sino versiones "definitivas" convenientemente testadas. Los paquetes disponibles en el servidor de CRAN están testados contra la versión actual de R. Mantenerse en una versión anticuada normalmente conduce a la pérdida de funcionalidad, errores de dependencias entre versiones de paquetes nuevos etc. En R, actualizar

You are right, maintainer does keep a list of model's packages.

Hi all, I thought I would post code to send an email out of R. The code uses Grothendieck and Bellosta's interface package rJython for executing Python from R. The code itself provides basic email functionality for email servers requiring authentication. It should be easy to extend it (e.g., for sending attachments). I hope it's useful. require(rJython) rJython <- rJython()

Hello, I've posted something similar under a different subject and never received a solution. Trying again with (hopefully) a better description. Objective: Send a matrix of string data in an email message. The message must have authentication and be sent via an R script. I'm almost there! Here is where I am at: I collect long error message lines in 'errs', which is a matrix.
