title: How to keep spaces in column names using write_excel_csv in R?
body: <p>I have a <code>data.frame</code> in which some of the column names have spaces, i.e. &quot;a a&quot;.</p>
  <p>All the elements of the data frame are characters.</p>
  <p>I use <code>write_excel_csv</code> (from <code>readr</code> package) to export the <code>data.frame</code>, since I want <code>utf-8</code> enconding. But, the spaces in the column names are replaced by dots, i.e. &quot;a.a&quot;.</p>
  <p>How can I keep the spaces in the column names?</p>
  <p>Note that when I use <code>write.csv</code>, the spaces are NOT replaced by dots, but I use <code>write_excel_csv</code> because of the <code>utf-8</code> enconding.</p>
