Dear Rama Giorgia,
if you are using R under Unix you should call R with
R --vsize=600M --nsize=25000k
Further, use scan() directly. It works much more better than
read.table().
Greetings

I have some difficulties in reading big dataset; I have to import a
dataset with 1'661'852 observations saved in a 51.4Mb - txt file.
I was wandering if this is a memory size problem or if I realy can't
import such big datasets. If the memory allocated to my R is not
enough, I would like to know exactly which comands I should use
in
order to read and use my large dataset.
I Looking forward to hearing from you.
