Deborah Siegel commented on SPARK-9713:
---------------------------------------
It seems that summary() on binomial classification model in glm is not
available as it is for gaussian model? Does SparkRWrappers.scala need to be
updated, or the documentation?
>dbwt <- createDataFrame(sqlContext, birthwt)
>logisticmodel <- glm(smoke ~ bwt, data = dbwt, family = "binomial")
>summary(logisticmodel)
