arrange(x, col, ...) ## S4 method for signature 'SparkDataFrame,Column' arrange(x, col, ..., withinPartitions = FALSE) ## S4 method for signature 'SparkDataFrame,character' arrange(x, col, ..., decreasing = FALSE, withinPartitions = FALSE) ## S4 method for signature 'SparkDataFrame,characterOrColumn' orderBy(x, col, ...)
x |
a SparkDataFrame to be sorted. |
col |
a character or Column object indicating the fields to sort on |
... |
additional sorting fields |
withinPartitions |
a logical argument indicating whether to sort only within each partition |
decreasing |
a logical argument indicating sorting order for columns when a character vector is specified for col |
A SparkDataFrame where all elements are sorted.
