title: Transposing a dataframe maintaining the first column as heading
body: <p>I have a big dataframe, but small example would be like this:</p>
  
  <pre><code>mydf &lt;- data.frame(A = c(letters[1:10]), M1 = c(11:20), M2 = c(31:40), M3 = c(41:50))
  </code></pre>
  
  <p>I want to transpose the dataframe and maintain the column 1 (A) as column heading ( letter[1:10]) as variable names. The following are scratch trials of unsuccessful codes. </p>
  
  <pre><code>tmydf = data.frame(t(mydf))
  names(tmydf) &lt;- tmydf[1,]
  </code></pre>
  
  <p>Thanks;</p>
