[R] Problems with xlsx and rjava

[Ivan Calandra]

I don't have any problem with xlsx/rJava:

 > library(xlsx)
Le chargement a nécessité le package : xlsxjars
Le chargement a nécessité le package : rJava
 > sessionInfo()
R version 2.15.1 (2012-06-22)
Platform: i386-apple-darwin9.8.0/i386 (32-bit)
locale:
[1] fr_FR.UTF-8/fr_FR.UTF-8/fr_FR.UTF-8/C/fr_FR.UTF-8/fr_FR.UTF-8
attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods base
other attached packages:
[1] xlsx_0.5.0     xlsxjars_0.4.0 rJava_0.9-3


Is it then a Windows problem?
