[jira] [Commented] (SPARK-15237) SparkR corr function documentation

["Sun Rui (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-15237?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15277454#comment-15277454 ] 

Sun Rui commented on SPARK-15237:
---------------------------------

SparkR supports two types of corr(), something like corr(SparkDataFrame, "col1", "col2") and corr(df$col1, df$col2). But the documentation of corr seems containing only the example for the latter.
[~felixcheung] how to fix the documentation?

> Please review the documentation of the corr function in SparkR, the example given: corr(df$c, df$d) won't run. The correct usage seems to be corr(dataFrame,"someColumn","OtherColumn"), is this correct? 
> Thank you.
