Thanks. I wasn't aware that scan or read.table allowed you to read in a
single line, process it, output results, and then read in the next line.
This is what I need to do because the data set is too large to hold in RAM.
I did manage to do this with readLines and overcome the space-delimiter
issue.
You can read a fixed number of lines, then process them; then you can
repeat. The key is to open the file as a connection before calling
read.table, and don't close it after each read. But you were probably
doing that with readLines.
