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
