plotKML can't install

[Shideler]

It appears that the plotKML dependency is not able to be installed as one of its dependencies "spcosa" has been archived and removed from CRAN.

Ok, I was able to solve this buy installing archived versions of plotKML and its dependancies. SPCOSA 0.3-7 and PlotKML 6.0

Having new issues with parallel computing. It's failing to create the cluster using your demo script. Will keep updated.
