title: error: Duplicated aesthetics after name standardisation: Ignoring unknown parameters: fun.y
body: <p>I'm trying to make a boxplot for some data I have and I've entered the following code:</p>
  
  <pre><code>rating_mean_plot &lt;- data %&gt;% 
    mutate(GROUP = recode(GROUP, "ontrol" = "control"), na.rm = T) %&gt;% 
    ggplot(aes(x = GROUP, y = ITEM_2, ITEM_1, ITEM_3)) + 
    labs(x = "Condition", y = "Mean Attractiveness Rating") +
    stat_summary(fun.data = "mean_cl_boot", geom = "errorbar", width = .25) +
    geom_point(stat = "summary", fun.y = "mean", size = 4, shape = 20, color = "red", fill = "grey") +
    ylim(0,7) +
    theme_cowplot()
  rating_mean_plot
  </code></pre>
  
  <p>However it has come up with the following errors</p>
  
  <pre><code>Duplicated aesthetics after name standardisation: Ignoring unknown parameters: fun.y
  
  No summary function supplied, defaulting to `mean_se()
  Removed 17 rows containing non-finite values (stat_summary)
  </code></pre>
  
  <p>any help on this would be greatly appreciated :)</p>
