mrg_cen_cols: Merge together observed concentrations and detection limits

In reasonabletools: Clean Water Quality Data for NPDES Reasonable Potential Analyses

Description

Merge a results column with a detection limits column by overwriting the censored results values with the corresponding detection limit.

Usage

mrg_cen_cols(qual, result, limit, nd = c("<", "nd", "ND"))

Arguments

qual	A character vector containing non-detect indicator strings, e.g., "<" or "ND". The strings used to indicate censored status can be edited in the "nd" argument.
result	A numeric vector of concentration measurements.
limit	A numeric vecotr of method detection limit/reporting limit values.
nd	A list indicating all the censoring flags included in the dataset. Defaults to "<", "nd", and "ND".

Value

A numeric vector.

Examples

result <- runif(5, 1, 10)
cen_result <- sample(c("<", ""), length(result), replace = TRUE)
method_limit <- rep(0.1, length(result))
result <- mrg_cen_cols(cen_result, result, method_limit)
print(data.frame(cen_result, result, stringsAsFactors = FALSE))
