result is that the default of <code>guess_max = min(1000, n_max)</code> produces better guessed column types that it used to. It should feel less necessary to fiddle with <code>guess_max</code> now.</p>

In fact vroom generally does this guessing better than readr currently does. Readr always uses the first guess_max number of rows for guessing, whereas vroom uses rows interspersed throughout the file if guess_max is less than the total number of rows.
