field.r(source: text, separator: text, index: number) 🡒 text, pure function

Returns the n^th field, zero-indexed from the right, in a text value that contains multiple sub-strings separated by a specified separator.

Example:

source = "a-b-c-d-"
show summary "" a1c3 with
  field.r(source, "-", 0) // returns ""
  field.r(source, "-", 1) // returns "d"
  field.r(source, "-", 2) // returns "c"

This function is intended to facilitate parsing values that have been concatenated within a single table column.
