Examples of integrating Hadoop and R. This directory contains the following: airline/ Examples which use the flight arrival and departure data available here: http://stat-computing.org/dataexpo/2009/the-data.html Note that this is the same data set used for many of the examples in the RHIPE documentation. The following examples are in this directory: airline/src/deptdelay_by_month/R/streaming/ - Example that uses the Hadoop streaming MapReduce interface to calculate average departure delay by month for each airline. airline/src/deptdelay_by_month/R/hive - Example using Hadoop Interactive for running MapReduce code to calculate average departure delay by month for each airline. airline/src/deptdelay_by_month/R/rhipe - Example using RHIPE to run MapReduce code that calculates average departure delay by month for each airline and then visualize the results. airline/src/deptdelay_by_month/R/rmr - Example using Revolution Analytics rmr package to calculate average departure delay by month for each airline. Instructions for running the code can be found with each example.
