Filter on attribute

[xmichael]

About
Takes a field name (string) and a text value (string) and checks which rows where field == “text”. Also takes an extra include(Boolean) parameter to indicate whether the the filter should include or exclude the values within the range

Notes

• The original code adds an extra boolean column to the original dataset to indicate test result and returns the modified dataset
• Not entirely sure it should be implemented. Adding primitive crude checks will never reach the flexibility of a full-fledged programming language.

Original code
Location pillar/cleaning/FilterOnAttribute

Leave unimplemented but note its existence. Such tests should be made obsolete by a proper DSL filter in PCAPI and/or FTOpen
