I cannot solve my problem with rjava on R.
When I install rJava package and require it, I have no issues .
install.packages("devtools")
install.packages("rJava")
library(rJava)
Sys.setenv(JAVA_HOME="C:/Program Files (x86)/Java/jre1.8.0_77")
devtools::install_github("kassambara/r2excel",INSTALL_opts="--no-multiarch")
When I compile the last line, I have this issue:
* installing *source* package 'r2excel' ...
** R
** preparing package for lazy loading
** help
*** installing help indices
** building package indices
** testing if installed package can be loaded
*** arch - i386
*** arch - x64
Error : .onLoad failed in loadNamespace() for 'rJava', details:

And I try using 32 bit R. but no change !
An other package called 'xlsx' needs rJava to run and I can use it.. I don't understand why..
R.version

Thanks for you help
Because the JDK you are using is 32 bit, reinstall the 64 bit from the Oracle Website
And then do :
Sys.setenv(JAVA_HOME="C:\\\PATH\\\TO\\\JAVA\\\")
library(rJava)
