title: How can I use tribble to transpose a numeric tibble?
body: <p>I try to follow the <code>tidyverse</code> approach and I extracted numerical data as tibble. As a matrix I would just transpose the data. There seems to be the function <code>tribble</code> in <code>tibble</code> for this but I can not make it work.</p>
  
  <p>How can I set the column names in the call? I can't see it from the help.</p>
  
  <pre><code>library(tidyverse)
  iris = as_data_frame(iris)
  iris = select(iris,-Species)
  
  tribble(iris)
  </code></pre>
  
  <p>gives the error</p>
  
  <blockquote>
    <p>Error: no column names detected in 'tribble()' call</p>
  </blockquote>
  
  <p>PS: I think there should be an easier way than doing <a href="https://stackoverflow.com/questions/28917076/transposing-data-frames">this</a>.</p>
