When I do it on a Mac installation I get:
Help for the topic "memory" was not found.
Is that a Linux-specific function? Or perhaps you meant to type:
?Memory
Which does produce useful information.

Subject: [R] Large Dataset
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
