Learning Bayesian Models with R

SparkR

Similar to RHadoop, SparkR is an R package that allows R users to use Spark APIs through the RDD class. For example, using SparkR, users can run jobs on Spark from RStudio. SparkR can be evoked from RStudio. To enable this, include the following lines in your .Rprofile file that R uses at startup to initialize the environments:

Sys.setenv(SPARK_HOME/.../spark-1.5.0-bin-hadoop2.6")
#provide the correct path where spark downloaded folder is kept for SPARK_HOME 
.libPaths(c(file.path(Sys.getenv("SPARK_HOME"),""R",""lib"),".libPaths()))

Once this is done, start RStudio and enter the following commands to start using SparkR:

>library(SparkR)
>sc <- sparkR.init(master="local")
