Thanks for the prompt reply. I think I have an idea on how to do what I want
now.
Best regards,

Good afternoon Hang,
This is an example of what I've done with a csv file with a header
which is too big to read into memory.
# this is a file with about 50 columns and 28 million records

Hi,
I have a very large data file(GB) from which I only want to extract one
column to draw histogram. This would be done several times, so I would like
to ask if there is anyway to plot this using R from the linux command line,
something look like this
cut -f1 xxx.txt |RplotHist
Thanks and h
