[R-sig-Geo] xlsx or rJava issue

[Dr Didier G. Leibovici]

A bit of dig up on google and I found 
(http://stackoverflow.com/questions/35179151/cannot-load-r-xlsx-package-on-mac-os-10-11) 
which resolves the thing in a terminal but when using Rgui same thing (?)

I tried re-installing in Rgui and now it is library(rJava) which cannot 
load (?)

library(xlsx)
Loading required package: rJava
Error : .onLoad failed in loadNamespace() for 'rJava', details:
   call: dyn.load(file, DLLpath = DLLpath, ...)
   error: unable to load shared object 
'/Users/lgzdl/Library/R/3.3/library/rJava/libs/rJava.so':
   dlopen(/Users/lgzdl/Library/R/3.3/library/rJava/libs/rJava.so, 6): 
Library not loaded: @rpath/libjvm.dylib
   Referenced from: /Users/lgzdl/Library/R/3.3/library/rJava/libs/rJava.so
   Reason: image not found
Error: package ‘rJava’ could not be loaded

but at least I can work with R in a terminal!

cheers to SanjayIV,

Didier
