Thank you very much, Brian.
It's clearly christal clear - but one needs a christal ball to realize
that! :-)
So I learned: architecture = bitness
On current Windows, yes.
But not on OS X nor Linux nor Solaris nor FreeBSD ....
It indicates the type of CPU, or more precisely the instruction set the
CPU is running. x86_64 CPUs (as used by most current Windows boxes) can
emulate i386 CPUs. So the architectures for R on Windows are
i386 (32-bit)
x64 (64-bit, the Windows name for x86_64).

Hello!
I installed rJava and am trying to load it.
library(rJava)
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: fun(libname, pkgname)
error: No CurrentVersion entry in Software/JavaSoft
registry! Try
re-installing Java and make sure R and Java have matching
architectures.
Error: package or namespace load failed for ‘rJava’
Any idea why?
Background info:
But the posting guide asked for the output from sessionInfo(): we
want to know what R knows it is running as, not why you think.
Windows 7, 64-bit
R version 3.0.1 (for 64-bit)
I just installed the lastest Java: Java 7 Update 21
For the right architecture?
The message is crystal clear: you do not have a Java installed
matching your R. Most likely your Java is 32-bit and your R 64-bit
or v.v.
