white space between title and plot in ioslides
<p>I am using the default theme of ioslides for a presentation, and I have difficulties with arranging a plot on the slide.</p>

<p>I use the following code for the respective slide:</p>

<pre><code>```{r crint1, fig.width = 7, fig.height = 5.5, fig.retina = NULL, fig.align="center"}
options(warn=-1)
load("path_to_data.RData")
ord &lt;- order(cor.table$COR)
barplot(cor.table$COR[ord], names.arg=cor.table$group[ord],horiz=T
        , cex.name=.6, border=F, space=.3, col="gray30", 
        xlab="Correlation Coefficient", las=1)
  grid(NULL, NA, col="white", lty="solid", lwd=0.7)
    abline(v=mean(cor.table$COR), lwd=2, lty=2, col="red")
      text(mean(cor.table$COR), 1, "Average", cex=.8, col="red", pos=4)```
</code></pre>

<p>Which results in this:</p>

<p><img src="https://i.stack.imgur.com/5RpXo.png" alt="link to image"></p>

<p>Which is okay, but I would like the plot to start right below the title and extend more on the slide, so the names of the rows are readable and don't overlap.</p>

<p>I tried to play around with <code>fig.height</code> and <code>fig.width</code>, but they only extend the size of the plot and do not change the starting coordinates (which makes the plot extend beyond the slide).</p>

<p>Is there any way to reduce the white space below the title and use that margin to extend the plot? I assume I have to edit the CSS for that particular slide, I am just not sure how. Any help is appreciated.</p>
