[R] Exporting large datasets

[DrDimo]

Hi all,

I am currently working on a particularly large (data wise) project, the
problem I am having is with exporting the data (for use later on). My
current sample dataset contains about 400million entries (approximately
20000 columns  x 20000 rows). I tried using the write.table command, but 8
hours later its still going. I will be trying write.matrix (MASS) next as it
is supposed to handle things a bit quicker, but I thought I would ask if
anyone has had experience with exporting large datasets and what is the
quickest method to do so.

Thanks in advance

-Dmitri
