The newest version of Spark (1.4) now comes with SparkR. Does anyone know how to go about installing the SparkR implementation on Windows? The sparkR.R script is currently located in C:/spark-1.4.0/R/pkgs/R/

[This](http://sgsong.blogspot.co.il/2015/06/how-to-use-sparkr-within-rstudio.html) appears to be a step in the right direction, but the instructions don't work for Windows as there is no sparkR directory as it relates to.
