SparkR : Where R meets Spark

R is one of the widely used Statistical tools. In recent years R is gaining lot of popularity and it is forecasted to beat SPSS and SAS in near future.
                                       
 R is

  • Open Source, used and supported by millions of people
  • Thousands of packages, most of which are used/developed by people in the statistics. ( I feel most of the products are developed by people who truly do not understand the end use case)

Cons
  • It runs on single core of processor,
  • Requires all data to be stored in RAM
  • Does not handle big data processing

   Here is where Spark comes in, Spark is designed for high speed big data processing or real time big data processing.
                                             
  • High speed processing, 100X times faster than hadoop.
  • Ease of use
  • shark,MLib,spark streaming makes spark really powerful.

  SparkR is a lightweight interface for spark through R. This aid the big data processing in R and results can be used in further statistics. 

How to install SparkR

   1. SparkR requires packages 
     require(devtools)
               require(rJava)

  2.   Install SparkR - this is a fairly easy step,
      install_github("amplab-extras/SparkR-pkg", subdir="pkg") 
More Information on github or Amplab SparkR
