ireadLines(con, n=1, ...)

`con`	a connection object or a character string.
`n`	integer. The maximum number of lines to read. Negative values indicate that one should read up to the end of the connection. The default value is 1.
`...`	passed on to the `readLines` function.

The line reading iterator.

  # create an iterator over the lines of COPYING
  it <- ireadLines(file.path(R.home(), 'COPYING'))
  nextElem(it)
  nextElem(it)
  nextElem(it)
