You could look at some extension packages, bigmemory for example. A recent
paper http://www.jstatsoft.org/v55/i14 (though for more developer-level
capabilities you would need to look at the package itself). Although the
big.matrix objects can't be used seamlessly as if they were matrices, they

Apologies in advance for errors/omissions, etc... that are my own
fault, not Simon's.

Ted,
Simon may be biased, but I am not. I'm barely a few days into
Rserve/FastRWeb and am blown away (and frustrated that I didn't have a
good excuse to give it a try sooner). I'm still in the process of
refining my setup (including a fresh installation of Apache2 on my
Ubuntu box), and have doc
Mike,
Neither bigmemory nor ff are "drop in" solutions -- though useful,
they are primarily for data storage and management and allowing
convenient access to subsets of the data. Direct analysis of the full
objects via most R functions is not possible. There are many issues

That must be it. Our new 3.0.0 has then added the Suggests, and as
the changes from 2.2.0 to 3.0.0 were unrelated I assumed we had been
properly suggesting previously; apparently not.
Thanks,

Yuri,
Based on your brief description, we have already done this with
bigmemory, and the ff package does something very similar but with
emphasis on a wide range of atomic data types and data frame. Unless
you are planning something different from what's been done before, you
shouldn't waste valu
Giuseppe,
I've been able to use NetWorkSpaces on all platforms, and have used
snow under Linux. It's possible to use snow under windows, but you'll
need to build the binary yourself I think. As an aside, I think this
makes it impossible to write a CRAN-friendly package that Requires: or

with a big R object). In which case this would not be a good way
to spend your time. I would encourage you to make sure you understand
other aspects of handling large objects with R before investing too
much time and effort in this one direction.

Hi Jay Emerson,
Our Intent
I was surprised to observe the following difference between 2.4.1 and
2.6.0 after a long overdue upgrade a few months ago of our
departmental server. It wasn't a bug fix, but a subtle improvement.
Here's the simplest example I could create. The size is excessive, on
the order of the Netflix Compe
ts. The check
requires looking for a pattern of objects; the pattern search may be avoided
by defining an object .noGenerics (with any value) in the package.
Naturally, if the package *does* have any such methods, this will prevent
them from being used.

colmean, where the use of exportMethods(colmean) fails, but
export(colmean) succeeds.
We can build and use the package by using export instead of exportMethods,
but we suspect that we're missing something that might be important to
understand.
Any hints or links to something we missed would
