big data?
Have you tried read.csv.sql from package sqldf? Peter On Tue, Aug 5, 2014 at 10:20 AM, Spencer Graves

What tools do you like for working with tab delimited text files up to
1.5 GB (under Windows 7 with 8 GB RAM)?
Standard tools for smaller data sometimes grab all the available RAM,
after which CPU usage drops to 3% ;-)
The "bigmemory" project won the 2010 John Chambers Award but "is not
available (for R version 3.1.0)".
findFn("big data", 999) downloaded 961 links in 437 packages. That
contains tools for data PostgreSQL and other formats, but I couldn't find
anything for large tab delimited text files.
Absent a better idea, I plan to write a function getField to extract a
specific field from the data, then use that to split the data into 4 smaller
files, which I think should be small enough that I can do what I want.
Thanks,
Spencer
