> I created a DataFrame. I added a logical column to the DataFrame using:
> sdfAdults <- withColumn(sdfAdults, "IsGT50K", sdfAdults$gt50==" <=50K")
> The resulting column was reported using str() as being of type logical, with values TRUE and FALSE.
> I subsequently ran the command:
> summary(sdfAdults)
> The command failed reporting that the mean could not be calculated on a column of type logical.
> Error in invokeJava(isStatic = FALSE, objId$id, methodName, ...) :
> org.apache.spark.sql.AnalysisException: cannot resolve 'avg(IsGT50K)' due to data type mismatch: function average requires numeric types, not BooleanType;
