R Theme River

Creates theme river using ggplot2. Note, that the R package ggplot2 hast to be installed in order to execute the R View node. The path to the installed R libraries has to be set to be able to load ggplot2. Change the path .libPaths("C:/Users/Kilian/Documents/R/win-library/3.0") to your R library path
