title: Circular plot with vectors in R
body: <p>I'm trying to create a circular plot with vectors of various magnitudes coming from the origin at various angles: something like the image below, although it doesn't have to be identical.  I've pored over <code>circular</code> and <code>circstats</code> and learned a lot about circular graphs, but not found anything quite like what I'm looking for.  I think I could crib something by hand if I had to but it just seems likely that someone more experienced than me has already written some code to do this.  </p>
