[R] How to separate huge dataset into chunks

Hello all,

I’m trying to take a huge dataset (1.5 GB) and separate it into smaller 
chunks with R.

So far I had nothing but problems.

I cannot load the whole dataset in R due to memory problems. So, I 
instead try to load a few (100000) lines at a time (with read.table).

However, R kept crashing (with no error message) at about the 6800000 
line. This is extremely frustrating.

To try to fix this, I used connections with read.table. However, I now 
get a cryptic error telling me “no lines available in input”.

Is there any way to make this work?
