[R-sig-Geo] plotKML::plotKML creates multiple errors in Google Earth (Ubuntu 14.10)

[Edzer Pebesma]

I can reproduce this under ubuntu 14.04 LTS. In my understanding, the
ubuntu (or linux) google-earth is by far not as good as it is under
windows or Mac OS-X, and this has been so for a long time. The only
solution I can think of is to work towards a solution without
google-earth, or make the switch to windows or mac.

Or is the story different with google-earth pro, which is now free?
