> SparkR can not output help information for SparkR:::summary correctly
> ---------------------------------------------------------------------
>
> Key: SPARK-11756
> URL: https://issues.apache.org/jira/browse/SPARK-11756
> Project: Spark
> Issue Type: Bug
> Components: R
> Reporter: Yanbo Liang
>
> R users often get help information for a method like this:
> {code}
> > ?summary
> {code}
> or
> {code}
> > help(summary)
> {code}
> For SparkR we should provide the help information for the SparkR package and
> base R package(usually stats package).
> But for "summary" method, it can not output the help information correctly.
> {code}
> > help(summary)
> Help on topic ‘summary’ was found in the following packages:
> Package Library
> SparkR /Users/yanboliang/data/trunk2/spark/R/lib
> base /Library/Frameworks/R.framework/Resources/library
> Choose one
> 1: describe {SparkR}
> 2: Object Summaries {base}
> {code}
> It can only output the help of describe(DataFrame) which is synonymous with
> summary(DataFrame), we also need the help information of
> summary(PipelineModel).
