Hello all.
Steven's approach didn't work for me. I'm running 64 bit R
> R.Version()
$platform
[1] "x86_64-pc-mingw32"
$arch
[1] "x86_64"
$os
[1] "mingw32"
$system
[1] "x86_64, mingw32"
and downloaded and installed the 64 bit version of Java directly from
Oracle. I then tried to load the rJava library and got
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'D:/Users/David
Stevens/Documents/R/win-library/2.15/rJava/libs/x64/rJava.dll':
LoadLibrary failure: %1 is not a valid Win32 application.
Error: package/namespace load failed for 'rJava'
I searched my computer for rJava.dll and found several (> 10) copies
scattered around.
d:\Oneida\CalWaipara>dir /s \rjava.dll

Is there something else I can try? Short of erasing and reinstalling
everything?
