-----------------------------------

             Summary: Use concrete data in SparkR DataFrame examples 
                 Key: SPARK-19819
                 URL: https://issues.apache.org/jira/browse/SPARK-19819
             Project: Spark
          Issue Type: Improvement
          Components: SparkR
    Affects Versions: 2.1.0
            Reporter: Wayne Zhang
            Priority: Minor


Many examples in SparkDataFrame methods uses: 
{code}
path <- "path/to/file.json"
df <- read.json(path)
{code}

This is not directly runnable. Replace this with real numerical examples so that users can directly execute the examples.
