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
ML

A little more detail would be appropriate. How large is "large"?
What is the format of the file? What do you wnat to do with the data?
Do you have to have it all in memory at once? Does it exist in a
data base already? What type of system are you running on? How much
memory do you have? ............
