-----------------------------------------
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
Reporter: Narine Kokhlikyan
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
