Usage

parallelize(sc, coll, numSlices = 1)

Arguments

`sc`	SparkContext to use
`coll`	collection to parallelize
`numSlices`	number of partitions to create in the RDD

Value

an RDD created from this collection

Examples

## Not run: 
##D sc <- sparkR.init()
##D rdd <- parallelize(sc, 1:10, 2)
##D # The RDD should contain 10 elements
##D length(rdd)
## End(Not run)
