title: R geom_bar facet_grid vertical instead of horizontal
body: <p>I am trying to make the same image I have but instead of horizontal each "propuesta", I want them to be in vertical. First "Propuesta A", under it "Propuesta B", and under this last one, "Propuesta C", as if each one of them is a separate graph, but together. I have the following code and output:</p>
  
  <pre><code>ggplot(articles_europaoccidental_sex_count_unique_group, aes(Country, percentage, fill = Gender)) + 
  +     geom_bar(stat = "identity", position = "dodge") + 
  +     facet_grid(~Propuesta) + geom_text(aes(label = round(percentage, 2)), position = position_dodge(width = 0.9), vjust = -1)
  </code></pre>
