| last {SparkR} | R Documentation |
Aggregate function: returns the last value in a group.
## S4 method for signature 'characterOrColumn' last(x, na.rm = FALSE) last(x, ...)
x |
column to compute on. |
na.rm |
a logical value indicating whether NA values should be stripped before the computation proceeds. |
... |
further arguments to be passed to or from other methods. |
The function by default returns the last values it sees. It will return the last non-missing value it sees when na.rm is set to true. If all values are missing, then NA is returned.
