Can you include the code you call spark.lapply?

Subject: sparkR 3rd library
Hi,
I am using spark.lapply to execute an existing R script in standalone
mode. This script calls a function 'rbga' from a 3rd library 'genalg'.
This rbga function works fine in sparkR env when I call it directly, but
when I apply this to spark.lapply I get the error
could not find function "rbga"

at org.apache.spark.rdd.RDD.computeOrReadCheckpoint(RDD.scala:323)
at org.apache.spark.rdd.RDD.iterator(RDD.scala
Any ideas/suggestions?
BR, Patcharee
