Introduction

CrunchR is an R wrapper for Apache Crunch that allows you to write MapReduce pipelines in R.

Prerequisites

For starters, you want to be running Linux-- we're not quite ready for OS X.

To use R Crunch, you need to have the following R packages installed locally:

  • rJava
  • roxygen2
  • bitops
  • RProtoBuf (optional)

You will also need the protocol buffer compiler, protoc, version 2.4.1 installed on your path.

Getting Started

We're still in the phase of getting everything to play nicely together. You can try everything out by running the following:

cd crunchR
./install-snapshot-rpkg.sh

Assuming that works well, there are some example R scripts under the examples directory that you can use to test out loading the crunchR library and running simple pipelines.
