Enhance reflection in RBackend. Automatically matching a Java array to Scala Seq when finding methods. Util functions like seq(), listToSeq() in R side can be removed, as they will conflict with the Serde logic that transferrs a Scala seq to R side.\r\n\r\n2.  Enhance the SerDe to support transferring  a Scala seq to R side. Data of ArrayType in DataFrame \r\nafter collection is observed to be of Scala Seq type.\r\n\r\n3.
