R: How to ignore case when using str_detect? : <p>stringr package provides good string functions.</p>

<p>To search for a string (ignoring case)</p>

<p>one could use</p>

<pre><code>stringr::str_detect('TOYOTA subaru',ignore.case('toyota'))
</code></pre>

<p>This works but gives warning </p>

<blockquote>
  <p>Please use (fixed|coll|regex)(x, ignore_case = TRUE) instead of ignore.case(x)</p>
</blockquote>

<p>What is the right way of rewriting it?</p>
