Simple question I am trying to lengthen the tick marks in ggplot2 on the axis - how? <pre class="prettyprint"><code>plot <- plot + theme(axis.ticks = element_line(colour = "black", size =2)) </code></pre> If increase the size it only seems to increase the width of them, not the length?

You need <code>axis.ticks.length</code>, i.e. <pre class="prettyprint"><code>plot + theme(axis.ticks.length = unit(1, "cm")) </code></pre>

Lengthen tick marks in ggplot2

Simple question I am trying to lengthen the tick marks in ggplot2 on the axis - how?

plot <- plot + theme(axis.ticks = element_line(colour = "black", size =2))

If increase the size it only seems to increase the width of them, not the length?
