Change bar plot colour in geom_bar with ggplot2 in r
<p>I have the following in order to bar plot the data frame.</p>

<pre><code>c1 &lt;- c(10, 20, 40)
c2 &lt;- c(3, 5, 7)
c3 &lt;- c(1, 1, 1)
df &lt;- data.frame(c1, c2, c3)
ggplot(data=df, aes(x=c1+c2/2, y=c3)) +
  geom_bar(stat="identity", width=c2) +
  scale_fill_manual(values=c("#FF6666"))
</code></pre>

<p>I end up having only grey bars: <a href="http://i.stack.imgur.com/zQGXd.png" rel="noreferrer">Grey bars for bar plot</a></p>

<p>I would like to change the color of the bar.
I already tried different scale_fill_manual from <a href="http://www.cookbook-r.com/Graphs/Colors_(ggplot2)/" rel="noreferrer">http://www.cookbook-r.com/Graphs/Colors_(ggplot2)/</a>
but still have grey bars.</p>

<p>Thank you for your help.</p>
