[Rd] Large vector support in data.frames

[Jan van der Laan]

What is the status of supporting long vectors in data.frames (e.g. 
data.frames with more than 2^31 records)? Is this something that is 
being worked on? Is there a time line for this? Is this something I can 
contribute to?

I now regularly work with datasets with more than 2^31 records and not 
being able to use data.frames is frustrating sometimes. I tried looking 
for information on this, but I probably looked in the wrong places 
and/or used the wrong search terms, and I could not find any information 
on this.

Best,
Jan
