trim_rows: Trim rows from a populated table without regard for table structure

Description

Trim rows from a populated table without regard for table structure

Usage

trim_rows(tt, criteria = all_zero_or_na)

Value

The table with rows that have only NA or 0 cell values removed.

Arguments

tt

(TableTree or related class)
a TableTree object representing a populated table.

criteria

(function)
function which takes a TableRow object and returns TRUE if that row should be removed. Defaults to all_zero_or_na().

Details

This function will be deprecated in the future in favor of the more elegant and versatile prune_table() function which can perform the same function as trim_rows() but is more powerful as it takes table structure into account.
