----------------------------
Hi [~Jassy]
After some investigation in the SparkR scripts, I found out that this error is
given when the object .sparkRjsc is not defined.
So I made a local modification in the SparkRInterpreter.scala that this field
is assigned to the SparkContext as follows:

After this change..the spark.lapply function works correctly.
Maybe it has todo with the Spark version I am using?
> Unable to use spark.lapply function it gives the error: "SparkR has not been
> initialized. "

> Hi,

> SparkR has not been initialized.
