[SPARK-10836] [SparkR] Added sort(x, decreasing, col, ... ) method to
DataFrame
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")
