[jira] [Commented] (SPARK-15545) R remove non-exported unused methods, like jsonRDD

["Miao Wang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-15545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15314416#comment-15314416 ] 

Miao Wang commented on SPARK-15545:
-----------------------------------

I did a search on all R files with setMethods and compare with NAMESPACE file. I have the following findings.
Dataframe.R:
toJSON
toRDD
map
flatMap
mapPartitions
foreachPartition

SQLContext.R
toDF
jsonRDD

context.R:
Only spark.lapply and setLogLevel are exported

functions.R:
is.nan
isnan

[~felixcheung] Can you review which ones from the above list should be removed?

Thanks!

> one reason to not remove this right away is because we have been talking about calling internal methods via `SparkR:::jsonRDD` for this and other RDD methods.
