Hi listeRs,
Maybe I have missed something, but I am facing a problem I don't understand
even after reading archives and manuals (…maybe not carefully enough !) :
64-bit rJava needs 64-bit Java: 32-bit rJava needs 32-bit Java. You can
install both on the same machine, and there are different registries
presented to 32- and 64-bit programs, so only the correct one will be
seen (if they are installed correctly).
In any case, rJava has its own help forums, so it you need further help,
ask there (and the maintainer does not read R-help routinely).
On my PC (64-bit OS, Intel Xeon CPU , two L5506@2.13 GHz processors, 12 Go
RAM) under Windows 7 SP1,
I run both 32-bit (i386-pc-mingw32/i386) and 64-bit (x86_64-pc-mingw32/x64)
version 2.14.2 (2012-02-29) of R, packages being updated daily.
Loading package "lsa" gives no problem under the 32-bit version :
------------------------------
library(lsa)
Le chargement a nécessité le package : Snowball
Le chargement a nécessité le package : RWeka
------------------------------
But does not work under the 64-bit version :
-------------------------------
library(lsa)
Le chargement a nécessité le package : Snowball
Error : .onLoad a échoué dans loadNamespace() pour 'Snowball', détails :
appel : NULL
erreur : .onLoad a échoué dans loadNamespace() pour 'rJava', détails :
appel : fun(libname, pkgname)
erreur : JAVA_HOME cannot be determined from the Registry
Erreur : le package ‘Snowball’ ne peut être chargé
--------------------------------
Because of the JAVA_HOME and Registry problem I suppose this is not strictly
related to R but rather to the R<-> Java communication, but I can't figure
what is happening, as it is working under the 32-bit configuration. Can
someone here help ?
Thanks by advance, all the best, Olivier
