Not long after submitting a new version of phytools (phytools 0.5-38) to CRAN,
which has been accepted, I discovered a weird bug in the interactive function
collapseTree is interactive, so it
is kind of hard to demo; however, a video of it's use can be seen
The bug is due to the plotrix function
draw.circle either no longer
being vectorized or not being correctly vectorized. I essentially fixed this
This fix is on GitHub and can be installed in the typical way.
