At tidytext 0.2.7, the default behavior for <code>collapse = NULL</code> changed to be more consistent. The new behavior is that text is <em>not</em> collapsed for <code>NULL</code>. </p> <p>Grouping data specifies variables to collapse across in the same way as <code>collapse</code> but you <strong>cannot</strong> use both the <code>collapse</code> argument and grouped data. Collapsing applies mostly to <code>token</code> options of "ngrams", "skip_ngrams", "sentences", "lines", "paragraphs", or "regex".</p> </td></tr> <tr valign="top"><td><code>...</code></td> <td> <p>Extra arguments passed on to <a href="../../tokenizers/html/tokenizers.html">tokenizers</a></p> </td></tr> </table> <h3>See Also</h3> <ul> <li> <p><code><a href="unnest_tokens.html">unnest_tokens()</a></code> </p> </li></ul> <h3>Examples</h3> <pre> library(dplyr) tweets <- tibble( id = 1, txt = "@rOpenSci and #rstats see: https://cran.r-project.org" ) tweets %>% unnest_tweets(out, txt) </pre> <hr /><div style="text-align: center;">[Package <em>tidytext</em> version 0.3.4 <a href="00Index.html">Index</a>]</div> </body></html>
