Dear Jim & Michael

the file contains 1000 lines and 1.200.000 columns, txt format and  i 
wish to read all the file with R if  possible, or  read a few columns?

I tried without success to turn bigmemory and colbycol packages, also 
scan and readLines  function but  It takes a long time without anything.

I have windows X64 bits 8 Go

In advance thanks
