Ivan, Simon,
Thanks for the replies.
I can work around the limitation. I currently either divide the data
into shards or use a list with (long) vectors depending on what I am
trying to do. But I have to transform between the two representations
which takes time and memory and often need more
The second point is not really an issue - R already uses numerics for
larger-than-32-bit indexing at R level and it works just fine for objects up to
ca. 72 petabytes.
However, the first one is a bit more relevant than one would think. At one
point I have experimented with allowing data frames
