Hi all,

 

I have an interesting project coming up, but the datasets are way bigger
than anything I've used before with R. I'll end up with a dataset with about
45,000,000 records, each with 3 columns. I'll probably want to add some more
columns for analysis if I can. My client can't deal with such big files, so
she is sending the data to me in chunks of "only" 4,500,000 records at a
time. The question is, can I get away with making one dataset/matrix out of
all 45 million records? It should be under 2 gigabytes total, but I don't
want the whole import process to fail after, say, 20 million records.

 

I'm running Windows 7 Home Premium, 64 bit version, with 8 GB of RAM and
plenty of hard drive space, but I'm planning to upgrade all that just for
this project, so that it will complete in my lifetime.

 

Thanks for any help!
