title: How to remove the "today" vertical line from my Gantt chart
body: <p>I've created a simple Gantt chart in R (my first) using the DiagrammeR package, but I can't work out how to remove the red vertical line (representing today) from the chart. Also, for some reason, March displays as w.17 on the x-axis rather than 03-17? Any ideas very welcome.</p>
  
  <p>Code is as follows</p>
  
  <pre><code>library(Diagrammer)
