Yanbo Liang commented on SPARK-11587:
-------------------------------------
Further more, I found that only "summary" method in package SparkR, others are
in package stats.
{code}
> showMethods("summary")
Function: summary (package SparkR)
x="DataFrame"
x="PipelineModel"
> showMethods("glm")
Function: glm (package stats)
formula="ANY", family="ANY", data="ANY"
formula="formula", family="ANY", data="DataFrame"
formula="formula", family="missing", data="data.frame"
(inherited from: formula="ANY", family="ANY", data="ANY")
> showMethods("predict")
Function: predict (package stats)
object="ANY"
object="PipelineModel"
{code}
> SparkR can not use summary.glm from base R

> When we use summary method of base R(not method of SparkR) in SparkR console:

> {code}
> It returns
