Hi,

I am looking for a way to search a file for position of some expression,
from within R. My current code:

 sha1Pos = gregexpr("<sha1>", readChar(filename,
file.info(filename)$size))[[1]]

Works fine for small files, but text files I will be working with might get
up to Gb range, so I was trying to accomplish the same without loading the
whole file into R.

I realize this is not what R is designed to do, but maybe there is some way
I am missing.
