This is asking for (probably) 4Gb of memory, which is quite a lot even
with 16Gb available.  The new (post1.2) memory manager should in principle
be able to allocate all the memory you can address, as long as no object
has more than 2^31 entries and there are no more than 2^31 objects, but I
don't think all the int vs long vs pointer details have been chased down
yet. I haven't heard of anyone using more than 2Gb for R, but if there is
anyone they are probably subscribed to this list...
