title: Merging two rows into one header using R
body: <p>I have performed an experiment analysis and now I have a huge list that unfortunately has two headers in the following way:</p>
  
  <pre><code>Image       Nuclei                  Cell
  Metadata_s  Children_Cells_Count    Intensity_IntegratedIntensityEdge_ERKStain
  C4          1                       39.03921669
  ...         ...                     ...
  </code></pre>
  
  <p>As there are 65 rows in this document (7x Image, 35x Nuclei and 23x Cells), I would like to have an automatic way using R to merge those two columns because I need them in the same column, as follows:</p>
  
  <pre><code>Image_Metadata_s    Nuclei_Children_Cells_Count     Cell_Intensity_IntegratedIntensityEdge_ERKStain
  C4                  1                               39.03921669
  ...                 ...                             ...
  </code></pre>
  
  <p>Does anybody of you know, how I could target this problem? I guess that there is a solution using the tidyverse librar, but so far I didn't find anything to solve this issue and I would be very helpful, if someone of you could help me.</p>
  
  <p>Thank you very much!</p>
