As per the help page for .Machine:
sizeof.pointer the number of *bytes* in a C SEXP type.
So:
8 bits per byte * 4 bytes = 32 bits
Also (outside of R) type "uname -a". This should give something like
Linux viggo 2.6.18.8-0.10-default #1 SMP Wed Jun 4 15:46:34 UTC 2008
x86_64 x86_64 x86_64 GNU/Linux
on a 64-bit system (SUSE in this case)
but
Linux turmalin 2.6.22.18-0.2-default #1 SMP 2008-06-09 13:53:20 +0200
i686 i686 i386 GNU/Linux
on 32-bitters
:-)
HTH,

Dear Prof. B.Ripley,
If :
.Machine$sizeof.pointer
[1] 4
2*2*2*2
[1] 16
So I am running with 16 bits?
How can I know the number of bits supported on my machine?
Kindly,

Look at .Machine$sizeof.pointer (in bytes).
