Librairies native R
by Eric Chatellier 28 Aug '14

28 Aug '14

Salut, Actuellement, les libs native jri sont committées dans le projet, mais elles sont spécifiques à chaque version de majeures de R. Pour R 3.0.x il faut les dll/so pour R 3.0 Il faudrait faire de multiples release à chaque version ce qui n'est pas top. On pourrait aussi supprimer le check de version dans ce fichier https://github.com/s-u/rJava/blob/master/jri/src/Rinit.c#L199 sachant que le test est faux, et que pour R 2.10 à 2.13, cela n'a pas posé de problème. Sauf que pour builder le dll ... voilà quoi :) L'autre possibilité demanderait une action utilisateur et lui demanderait d'installer le package R 'rJava' (aka le support java dans R), il serait fournir par R. Le point génant est la ligne de commande ensuite pour réussir à trouver le fichier jri.dll ou libjri.so: java -Djava.library.path=$R_HOME/library/rJava/jri Qu'en pensez-vous ? -- Éric Chatellier - www.codelutin.com - 02.40.50.29.28

Problème de licence
by Eric Chatellier 09 Feb '12

09 Feb '12

Bonjour, En ces temps de réflexions constructives sur les licences, il se trouve qu'en vérifiant la licence de nuiton-j2r, celle ci s'avère potentiellement incorrecte. En effet, nuiton-j2r est en LGPL: http://maven-site.nuiton.org/nuiton-j2r/license.html Mais la dépendance jri (rJava) est GPL: http://cran.r-project.org/web/packages/rJava/index.html R est également GPL: http://www.r-project.org/Licenses/ nuiton-j2r ne devrait-il pas être en GPL ? -- Éric Chatellier <chatellier(a)codelutin.com> Tel: 02.40.50.29.28 http://www.codelutin.com

Hi, I'm encounterring another NPE if I try this call: rengine.eval("sa <- fast99( factors = 3, n = 1000, q = c('qunif','qunif','qunif'), q.arg = list(list(-1,1),list(-1,1),list(-1,1)))"); The R call passes in R, buf fails in j2r with output: 12 mai 2010 16:30:26 org.nuiton.j2r.RProxy initOnNet INFO: Trying to initialize the R Proxy with Network 12 mai 2010 16:30:26 org.nuiton.j2r.net.RNetEngine init INFO: Trying to connect to the Rserve on '127.0.0.1:6311' 12 mai 2010 16:30:26 org.nuiton.j2r.net.RNetEngine convertResult GRAVE: Unknown return type on : org.rosuda.REngine.REXPSymbol[fast99] 12 mai 2010 16:30:26 org.nuiton.j2r.net.RNetEngine convertResult GRAVE: Unknown return type on : org.rosuda.REngine.REXPSymbol[list] 12 mai 2010 16:30:26 org.nuiton.j2r.net.RNetEngine convertResult GRAVE: Unknown return type on : org.rosuda.REngine.REXPSymbol[list] 12 mai 2010 16:30:26 org.nuiton.j2r.net.RNetEngine convertResult GRAVE: Unknown return type on : org.rosuda.REngine.REXPSymbol[-] Exception in thread "main" java.lang.NullPointerException at org.nuiton.j2r.net.RNetEngine.convertResult(RNetEngine.java:302) at org.nuiton.j2r.net.RNetEngine.convertResult(RNetEngine.java:293) at org.nuiton.j2r.net.RNetEngine.convertResult(RNetEngine.java:293) at org.nuiton.j2r.net.RNetEngine.convertResult(RNetEngine.java:293) at org.nuiton.j2r.net.RNetEngine.convertResult(RNetEngine.java:293) at org.nuiton.j2r.net.RNetEngine.eval(RNetEngine.java:169) at org.nuiton.j2r.RProxy.eval(RProxy.java:154) at org.simexplorer.test.sensitivity.Fast99.main(Fast99.java:33) In the sample, the vector and lists for the domains are superfluous because identical for each factor, but I need this format for other cases.

NPE with j2r
by Nicolas Dumoulin 12 May '10

12 May '10

Hi, I'm trying to use j2r with the sensitivity R package http://cran.r-project.org/web/packages/sensitivity/index.html I've installed R 2.10.1, sensitivity 1.4.0 and Rserve 0.6-1. Following commands are OK in the R shell: library('sensitivity') fast99(model = NULL,factors=3,n=1000,q='qunif',q.arg=list(min=-1,max=1)) but if I try the same with j2r, I've got: Exception in thread "main" java.lang.NullPointerException at org.nuiton.j2r.net.RNetEngine.convertResult(RNetEngine.java:302) at org.nuiton.j2r.net.RNetEngine.convertResult(RNetEngine.java:293) at org.nuiton.j2r.net.RNetEngine.convertResult(RNetEngine.java:293) at org.nuiton.j2r.net.RNetEngine.convertResult(RNetEngine.java:293) at org.nuiton.j2r.net.RNetEngine.eval(RNetEngine.java:169) at org.nuiton.j2r.RProxy.eval(RProxy.java:154) My java code is: Engine rengine = new RProxy(); rengine.eval("library('sensitivity')"); rengine.eval("fast99(model = NULL,factors=3,n=1000,q='qunif',q.arg=list(min=-1,max=1))"); If someone have an idea… -- Nicolas Dumoulin Ingénieur d'études - Cemagref, LISC +33 (0)4.73.44.07.29

Re: [Nuiton-j2r-devel] [Rd] Bug in R evaluating a huge instruction (PR#14096)
by Jean Couteau 03 Dec '09

03 Dec '09

Thank you very much for your input Duncan and Romain. I will try to do what you are advising. The R instruction is generated from java using jri (and an abstraction layer we built upon it : nuiton-j2r), i will try add this limitation to nuiton-j2r so that it split the instruction if it is too long.

Migration du projet / Project migration
by root＠nuiton.com 04 Aug '09

04 Aug '09

Bonjour à tous, Dans l'optique de dissocier au maximum les projets libres initiés par la société Code Lutin de celle-ci et permettre une meilleur implication de la communauté du libre dans ces derniers, nous vous annonçons que le site de développement du projet n'est plus hébergé sur le labs libre-entreprise mais sur la plateforme www.nuiton.org. La plupart de la migration a été réalisée, nous vous invitons à utiliser d'ors et déjà la plateforme http://www.nuiton.org (le projet sur le labs libre-entreprise n'est plus accessible publiquement) Les listes de diffusions ont été migrées et tous les utilisateurs ont normalement du être réabonnés aux nouvelles listes. La nouvelle adresse de cette liste: nuiton-j2r-devel(a)list.nuiton.org Nous sommes désolés des désagréments causés et vous remercions de votre soutien. Cordialement, L'équipe de développement. ---------------------------- Dear all, In order to separate the libre projects that Code Lutin has initiated and the company itself, and also to encourage the implication of the libre community, we recently moved the project's development site from the libre-entreprise labs to the www.nuiton.org platform. Most of the migration is complete, we invite you to use, from now on, the platform http://www.nuiton.org (the project on libre-entreprise labs is now longer publicly available). The mailing-lists have been migrated and everybody should have been automatically subscribing the new lists. New mail address for this list: nuiton-j2r-devel(a)list.nuiton.org We are sorry for the inconvenience, and thank you for your support. Best regards, The development team.
