Hello,
I am wondering if I am misinterpreting something from R/3.0.0 NEWS
LONG VECTORS:
This section applies only to 64-bit platforms.
...
o serialize() to a raw vector is unlimited in size (except by
resources).
However when I try the following it fails:
> foo <- raw(2500000000)
> print(object.size(foo),units="auto")
2.3 Gb
> bar <- serialize(foo, NULL)
Error: serialization is too large to store in a raw vector
However this works:
> foo <- raw(2000000000)
> print(object.size(foo),units="auto")
1.9 Gb
> bar <- serialize(foo, NULL)
So it appears there may be a 2GB limit, which I've read should only be the case
for 32-bit or pre-R/3.0.0 installations.
