How to read data file quickly?
I have a huge text file (~500 MB). The file is too large to
Import into Mathematica, although I can read it in Emacs.
Is there a way to tell Mathematica to
Read in only line number 23681 (where lines are delimited by
"\r", in the typical way, I think)? For example, suppose that I have:
str = OpenRead["test.txt"];
For a text file,
SetStreamPosition seems to refer to the character number, not the line number. Is there any way to change this? Thank you for your time.
