How to display pivoted scala rdd?

[#1]

Trying to display pivoted RRD with Scala, either directly or by converting to dataframe. However, take(), toDF(), and show all produce similar errors - not a member of org.apache.spark.sql.GroupedData import org.apache.spark.sql.SQLContext._

val meterdata = sqlContext.read.format("com.databricks.spark.csv").option("delimiter", ",").option("header", "false").load("/CBIES/meters/")

val meters = meterdata.groupBy("C0").pivot("C1")

meters.toDF meters.take(10).foreach(println)

<console>:71: error: value toDF is not a member of org.apache.spark.sql.GroupedData

error: value take is not a member of org.apache.spark.sql.GroupedData

<console>:83: error: value show is not a member of org.apache.spark.sql.GroupedData error: value toDF is not a member of org.apache.spark.sql.GroupedData
