title: ggplot2, unwanted naming in Y-axis
body: <p>Let's say I have following data:</p>
  
  <pre class="lang-r prettyprint-override"><code>df &lt;- data.frame(
       "Values" = c("Gender","Gender","Marital Status","Marital Status","Age","Age"),
       "Mean"= c(0.6934877,  0.8536885,  0.8801737,  0.8998975, 54.6858177, 54.1486680),
       "By"= c("Urban", "Rural", "Urban","Rural","Urban", "Rural")
  )
  </code></pre>
  
  <pre class="lang-r prettyprint-override"><code>df$Values &lt;- factor(df$Values)
  
  levels(df$Values)
  
  df_groupby &lt;- df %&gt;%
        dplyr::group_by(Values) 
  </code></pre>
  
  <p>Expected results on the y-axis  Gender, Marital Status, Age same as in <code>df</code>.  Many thanks in advance</p>
  
  <p>I tried that without success</p>
  
  <pre class="lang-r prettyprint-override"><code>ggplot(df_groupby , aes(Values, Mean)) +
        geom_bar(stat = "identity") +
        coord_flip()
  </code></pre>
