Hi All, I'm having issues with quiver, and quiverkey() although, I have never experienced these issues in the past. I attached an image to this post that demonstrates that quiver_key() used to work for me, this image was generated on 17-Jul-2014. However, if I run this exact same code (see below for the code), the quiver key reference on the top right does not get plotted, but the text will. I haven't changed anything, but I think there have been some package updates between then and now. For what it's worth, I've tried many different ways to generate the quiverkey() and haven't had any luck. Has anyone else experienced similar issues?
Thanks for any insights!
