[R] how to read a file one line at a time?

[Terry Westley]

Is there a way to read a file one line at a time?
My file is potentially very large (multiple gigabytes)
so I'd like to read and process one line at a time.

The only choices I see are:

1) Direct the file to standard input and use readline(),
   but then I have to parse the data columns myself.

2) Call scan() with nlines=1 over and over again, incrementing
   skip, but I suspect that it will read the whole file each
   time.

Any suggestions?
