You could do a mapPartitions and Filter within each partition -- Something like
numbers <- parallelize(sc, 1:20, 4L)
evenNumbers <- lapplyPartition(numbers, function(part) { Filter(
function(x) { x%%2 == 0} , part) })
collect(evenNumbers)
It should be simple to add this to the SparkR API as well -- Let me
know if you want to send a PR !
