             Summary: Add SparkR sort function to dataframe
                 Key: SPARK-10836
                 URL: https://issues.apache.org/jira/browse/SPARK-10836
             Project: Spark
          Issue Type: Sub-task

            Priority: Minor


Hi everyone,

the sort function can be used as an alternative to arrange(... ).
As arguments it accepts x - dataframe, decreasing - TRUE/FALSE, a list of orderings for columns and the list of columns, represented as string names

for example: 
 sort(df, TRUE, "col1","col2","col3","col5") # for example, if we want to sort some of the columns in the same order

 sort(df, decreasing=TRUE, "col1")
 sort(df, decreasing=c(TRUE,FALSE), "col1","col2")


Thanks,
Narine
