title: How to get filled points when you use geom_point() in a ggplot graphic
body: <p>Hi dear I am working with two continuous variables. When I made a ggplot graphic I used this code:</p>
  
  <pre><code>p4 &lt;- ggplot(DataBase, aes(x=x, y=y))+xlab("Porcentaje de Tamaño Acumulado")+ylab("Porcentaje de Monto Acumulado")
  p4 + geom_line(colour="darkblue",size = 1.5)+geom_point(colour = "red", size = 4,,shape=5)
  </code></pre>
  
  <p>I got this picture:</p>

  <p>Where the points are empty. It is possible to fill them. I tried with <code>fill</code> but I got the same result. Thanks.</p>
