tail() function

Warning! This page documents an earlier version of Flux, which is no longer actively developed. Flux v0.65 is the most recent stable version of Flux.

The tail() function limits each output table to the last n records. The function produces one output table for each input table. Each output table contains the last n records before the offset. If the input table has less than offset + n records, tail() outputs all records before the offset.
