I have some issues with your rounding in the legends. If the different radii are orders of magnitude apart, the rounding is not consistent, which seems to lead to a non-natural legend.
Things can get even worse when two roundings lead to the same number:
Maybe you can round all the radii to the same number of digits?

Furthermore, there are some base-R rounding functions available (I saw that you implemented your own function). https://stat.ethz.ch/R-manual/R-devel/library/base/html/Round.html
