conama_check: CONAMA conformity check (detailed; default class = "2")

Description

For each parameter present in df, adds columns:

• *_ok (logical),

• *_status one of "ok", "acima_do_maximo", "abaixo_do_minimo",

• *__lim_min and *__lim_max (thresholds used),

• *__delta (difference to the relevant limit; >0 above max, <0 below min, 0 if ok).

If multiple limit rows exist for the same parameter, *_ok is TRUE if any row is satisfied; for status/lim_min/lim_max/delta, the first satisfied row is chosen; if none satisfy, the row with the smallest absolute violation (min |delta|) is used.

Usage

Value

The input df with additional columns per parameter as described.

Arguments

A tibble/data.frame with parameter columns (e.g., ph, turbidez, od, dbo).
