Complete UNE-EN 689 preliminary assessment (high-level wrapper) — une689_evaluate

Calculates the ED and IE for each day and classifies the overall conformity, from a set of samples organised by measurement day. Designed to be used directly from code, without going through the Shiny application.

Usage

une689_evaluate_preliminary(data, vla)

Arguments

data: A data.frame in long format with columns day (day identifier, numeric or character), concentration (mg/m3) and time (hours). One row per sample.
vla: Numeric. Valor Limite Ambiental / occupational exposure limit (mg/m3).

Value

A list with two elements:

days_table: A data.frame with columns day, ED and IE, one row per day.
result: Character scalar with the overall classification, see une689_classify_conformity().

Examples

data <- data.frame(
  day = c(1, 1, 2, 3, 3),
  concentration = c(12, 8, 9, 5, 6),
  time = c(4, 4, 8, 3, 5)
)
