[datatable-help] Need help with fread function

[vishal]

I am trying to read 2.5GB pipe delimited text file in R using fread but I am
getting below error.
   
"  Opened file ok, obtained its size on disk (-0.0MB), but couldn't memory
map it. This is a 32bit machine. You don't need more RAM per se but this
fread function is tuned for 64bit addressability, at the expense of large
file support on 32bit machines. You probably need more RAM to store the
resulting data.table, anyway. And most speed benefits of data.table are on
64bit with large RAM, too. Please either upgrade to 64bit (e.g. a 64bit
netbook with 4GB RAM can cost just £300), or make a case for 32bit large
file support to datatable-help."
   
I have used following syntax. 
setwd("E:/Projects/Alo") 
library(data.table) 
f <- fread("6.txt",header="auto")
