dql_accuracy: Assign accuracy Data Quality Levels (DQLs) to continuous data

In DEQrmichie/odeqcdr: ODEQ Continuous Data Review

Assign accuracy Data Quality Levels (DQLs) to continuous data

Description

This function assigns an accuracy data quality level to parameters measured in the field using pre- and post-deployment checks. The data quality levels are assigned following DEQ’s Data Quality Matrix (DEQ, 2013). The data quality matrix defines the accuracy and precision criteria for equipment calibration and field audits respectively respectively.

Usage

dql_accuracy(prepost, results, prepost_only = FALSE)

Arguments

prepost	Data frame of the prepost data generated using contin_import.
results	Data frame of the results data generated using contin_import.
prepost_only	Boolean to indicate if the prepost data frame should be returned with a new columns for the accuracy DQL, and absolute difference between the result and references values. Default is FALSE.

Details

use dql_precision to assign the data quality level using field duplicates, field audits, or split samples.

Inputs into this function must retrieved from Oregon DEQ's continuous data submission template xlsx file v2.03. Use contin_import to get the list that hold the data frames used for this function's inputs.

Value

Vector of the precision DQL indexed in the same order as the result input. Or if audit_only=TRUE a data frame.
