The sqldf package makes it easy to use DBI, RSQLite and sqlite
to read a large file directly to an sqlite database without going through
R and then read all or a portion of it into R using an arbitrary SQL
statement. See example 6 on the home page: http://sqldf.googlecode.com

With smaller tab-limited files, I could load them using read.table and the
likes. Now I have a gigantic 10^8 rows and 1^3 columns tab-limited file for
processsing, please throw some ideas how to handle it.
Thanks
