Hola, Tengo un problemillo con el encoding de unas palabras y trabajarlas en R por medio de rJython. Os explico: cuando quiero utilizar cualquier dato que contenga acentos o eñes o cualquiera de estos caracteres que no usan los angloparlantes obtengo un error. Ejemplo, en R: > jython.call(rJython,''ascii'',''señoría'') Error en jython.exec(rJython, jython.comm...

Dear R users, I have been using rsympy to solve a set of simultaneous equations from R. There are two solutions for the variable I'm interested in, xx[0] and xx[1], which are in terms of symbols called lam and conc. I'd like to pick out the one which is positive at (lam=0, conc=0) and call it mysol. In python I could write: if (xx[0].subs(lam,0)).subs(conc,0)>0: mysol=xx[0]

...anguages that throw exceptions more rarely (just about everyone), dwarf-exceptions should be cheaper. Dwarf-exceptions will still be worth investigating for Python eventually; we're just not prioritizing it. Anyone who wants us to prioritize it higher should bring data. :) IronPython's and Jython's experiences are interesting too. IronPython has had big problems with the cost of exceptions on the .NET platform. Jython has _not_ had problems in the JVM, which indicates that the two big virtual machines have made different tradeoffs for this. That would make me very hesitant to say that e...

...ode would presumably be helpful anyway. Surely there could be some sort of process to generate automated jni bindings? I don't think a Java implementation of the R parser is as bigger task as it seems ... much of the work to get an interpreted scripting language working could be taken from the Jython project?

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 uso aparecen en otras plataformas y con otras...

Much bigger crowd actually :-) - this will work for Scala, Clojure, Jython and all the other cool JVM languages too. (I''ll be doing something similar for .NET, which will bring Cucumber goodness to C#, F# and whatever languages run on .NET. But IronRuby must catch up on speed first). I had the pleasure of going back to visit PicoContainer - a pioneering lightwei...

Then I collapse them into a character vector via: errs = paste(errs, collapse = "") Then I send that in a email via rJython.

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() rJython$exec( "import smtplib" ) rJ...

...code (IL) from Python code. Rather, it is an integration of the C Python engine with the .NET runtime. This approach allows you to use CLR services and continue to use existing Python C extensions while maintaining native execution speeds for Python code." 2. "While a solution like Jython provides 'two-way' interoperability, this package only provides 'one-way' integration. Meaning, while Python can use types and services implemented in .NET, managed code cannot generally use classes implemented in Python." 3. "Python for .NET is based on Python 2.3.2....

...vitably breaks psycopg2 (which I've blitzed & reinstalled on top of the new Python build, seems like dozens of times now). It's a really strange problem-- the recompiled/installed psycopg2 *is* looking for the right modules (PyUnicodeUCS4-[whatever]), but not finding them. Did a clean Jython reinstall too, as that's the only thing which contains the purported PyUnicodeUCS4 stuff that seems to be missing). Long story short, I've been banging my head for a couple of days now trying to get my system to play nice w/a ucs4-built app (Xapian), & it ain't happening, so I tho...

...efaultImpl (moreover, both the calls return "0" ). I do not know the libvirt internals, so my question is : it is possible to call the libvirt events calls using java binding? Can you tell me the issues involved in this task? I'm thinking to build a native library and use jni or use jython as alternatives. Thanks, Maurizio

In the "Introduction and preliminaries" the "An Introduction to R" manual says about R: "... Among other things it has ... a well developed, simple and effective programming language (Called 'S') ... ". Now I'm a little confused. This means that language S is a component part of R? And S is not free? But R is free? Or the mentioned S is only "a free

Hi Everyone I am considering learning Java. There have been well publicized Java security incidents recently that make me not want to learn it. However it's in Centos and I trust Centos, are the concerns in the media blown out of proportion ? -Patrick
