Hi alI,

I  have a 3.1 GB Dataset ( with  11 coloumns and lots data in int and string). 
If I use read.table; it takes very long. It seems that my RAM is not big 
enough (overload) I have 3.2 RAM and  7GB SWAP, 64 Bit Ubuntu.

Is there a best sultion to read a large data R? I have seen, that people 
suggest to use bigmemory package, ff. But it seems very complicated.  I dont 
know how to start with that packages.

i have tried to use bigmemory. But I got some kind of errors.  Then I gave up.


can someone give me an simple example how ot use ff or bigmemory?or maybe re 
better sollution?



Thank you in advance,


Edwin
