Simon,
Though we're please to see another use of bigmemory, it really isn't
clear that it is gaining you
anything in your example; anything like as.big.matrix(matrix(...))
still consumes full RAM for both
the inner matrix() and the new big.matrix -- is the filebacking really
necessary. It also doesn't
appear that you are making use of shared memory, so I'm unsure what
the gains are. However,
I don't have any particular insight as to the subsequent problem with
NeweyWest (which doesn't
seem to be using the big.matrix objects).

Dear R users,
I am using R right now for a simulation of a model that needs a lot of
memory. Therefore I use the *bigmemory* package and - to make it faster -
the *doMC* package. See my code posted on http://pastebin.com/dFRGdNrG
