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

[Guido Schulz]

I briefly tried cesium, but I couldn't manage to open a local KML file
with it. But it is supposed to work somehow...

Google Earth Pro has only the Linux binaries for download at the moment,
but I might give it a try...

In the end, I really might have to install Windows 7 for a dual boot...

Best,

G
