Rmpi long vector support

Aha, thanks again.  

Two notes:
1) serialize() didn't work over 2^31 until 3.0.1 (so it failed in my 3.0.0, with a message that led me to believe that there was still a 32-bit limit on length).

2) more puzzling: Using vectors over 2^31 (2^31+2 ?!) seems to be broken in Rstudio, even though it works in R command-line. It looks like the functions that monitor the workspace are not ready yet.

Anyway, the important thing is, this message:
    "Error: long vectors not supported yet: ../include/Rinlinefuns.h:100"
is from Rstudio, not R.

Simon, I don't understand this either: It seems that R is commonly indexed
by 32-bit pointers, and mine certainly is on my Mac.

Nope, since R 3.0.0 we use 64-bit binaries on Mac OS X:

$ R
R version 3.0.1 Patched (2013-07-15 r63328) -- "Good Sport"
Copyright (C) 2013 The R Foundation for Statistical Computing
Platform: x86_64-apple-darwin10.8.0 (64-bit)
[...]

.Machine$sizeof.pointer

[1] 8

I'll get the message
above also, as did the OP; that was the direct problem. How do I get "52
bit" R?

However, on a win7 64 with R 3.0.1 (16GB ram), I got

n=6e8
x=integer(n)
a=serialize(x,NULL)
