title: Customize vline of love.plot (cobalt package)
body: <p>I would like to customise the automatically generated vline at xintercept =0 of the default <code>love.plot</code> (which is generated as a ggplot object).</p>
  <p><a href="https://cran.rstudio.com/web/packages/cobalt/vignettes/cobalt_A4_love.plot.html" rel="nofollow noreferrer">https://cran.rstudio.com/web/packages/cobalt/vignettes/cobalt_A4_love.plot.html</a></p>
  <p>I tried to override the vline by:</p>
  <pre><code>plot+ geom_vline(xintercept = 0, linetype = &quot;dashed&quot;, color = &quot;red&quot;, size = 0.4)
  </code></pre>
  <p>but the command only superposes the new line on the existing one.</p>
  <p>Many thanks</p>
