<p>I’m pleased to announce version 1.1.0 of stringr. stringr makes string manipulation easier by using consistent function and argument names, and eliminating options that you don’t need 95% of the time. To get started with stringr, check out the <a target="_blank" href="http://r4ds.had.co.nz/strings.html">strings chapter</a> in <a target="_blank" href="http://r4ds.had.co.nz/">R for data science</a>. Install it with:</p>
<pre><code>install.packages(&quot;stringr&quot;)</code></pre>
<p>This release is mostly bug fixes, but there are a couple of new features you might care out.</p>
<ul>
<li>There are three new datasets, <code>fruit</code>, <code>words</code> and <code>sentences</code>, to help you practice your regular expression skills:
<pre><code>str_subset(fruit, &quot;(..)\\1&quot;)
#> [1] &quot;banana&quot;      &quot;coconut&quot;     &quot;cucumber&quot;    &quot;jujube&quot;      &quot;papaya&quot;     
#> [6] &quot;salal berry&quot;
head(words)
#> [1] &quot;a&quot;        &quot;able&quot;     &quot;about&quot;    &quot;absolute&quot; &quot;accept&quot;   &quot;account&quot;
sentences[1]
#> [1] &quot;The birch canoe slid on the smooth planks.&quot;</code></pre>
</li>
<li>More functions work with <code>boundary()</code>: <code>str_detect()</code> and <code>str_subset()</code> can detect boundaries, and <code>str_extract()</code> and <code>str_extract_all()</code> pull out the components between boundaries. This is particularly useful if you want to extract logical constructs like words or sentences.
<pre><code>x &lt;- &quot;This is harder than you might expect, e.g. punctuation!&quot;
x %>% str_extract_all(boundary(&quot;word&quot;)) %>% .[[1]]
#> [1] &quot;This&quot;        &quot;is&quot;          &quot;harder&quot;      &quot;than&quot;        &quot;you&quot;        
#> [6] &quot;might&quot;       &quot;expect&quot;      &quot;e.g&quot;         &quot;punctuation&quot;
x %>% str_extract(boundary(&quot;sentence&quot;))
#> [1] &quot;This is harder than you might expect, e.g. punctuation!&quot;</code></pre>
</li>
<li><code>str_view()</code> and <code>str_view_all()</code> create HTML widgets that display regular expression matches. This is particularly useful for teaching.</li>
</ul>
