CalcThemAll.PRM (version 1.1.1)

treat_LORs: Treat a single observations LORs

Description

Treat a single observations LORs

Usage

treat_LORs(
  sample_data,
  pesticide_info = CalcThemAll.PRM::pesticide_info,
  treatment_method = "Zero"
)

Value

returns the provided data set with the first row's LOR values treated.

Arguments

sample_data

A single observation containing a concentration value for each pesticide being used in the metric. LOR values should be in "<0.05" format and no values should be empty "".

pesticide_info

The reference table which contains all relevant information for calculations. It is recommended that the "pesticide_info" dataset included in this package be used and if you wish to include more or less pesticides you can appended them with the relevant information to this table. If you are creating your own table you must ensure that the pesticide name column is title "pesticides" and the relative LOR replacement column is "relative_LOR" for the function to run.

treatment_method

Select how to treat the LOR values with either "WQI" representing the Queensland Department of Environment & Science Water Quality Monitoring & Investigations team's method for replacing LORs or "Zero" which replaces them with a negligible numeric value. Zero is the default here as this function on its own only treats a single observation and therefore the first detection in the WQI method cannot be used.

Examples

first_sample <- Canto_pesticides[1,] #this selects only the first row (sample)
LOR_treated_first_sample <- treat_LORs(sample_data = first_sample,
pesticide_info = CalcThemAll.PRM::pesticide_info, treatment_method = "Zero")
print(LOR_treated_first_sample)
