[Rd] Vector binding on harddisk

[_]

Hi all,
Using big vectors (more than 4GB) is unfortunately not possible under 
Windows or other OS's if not enough RAM exists.
Could it be possible to implement an a new data type in R, like a 
vector, but instead holding the information in memory, the data lies on 
an file. If data is accessed, the data type vector get the information 
automatically from the file.
There is a package out there (named ff) but the accessed boundary have 
to be declared by the user this is a disadvantage.

Greetings.
