Merge auxiliary variables with data

Usage

merge_auxiliary(data, info, determinands)

Arguments

data: a data frame containing the contaminant data in long format, both the contaminants to be assessed and their auxiliary variables
info: a harsat info object
determinands: a character string given the identifiers of the determinands that are to be assessed

Value

a data frame containing the contaminant data in wide format, with the auxiliary variables pivoted to match the determinands they are linked to

Details

info$determinand identifies which auxiliary variables are linked to each determinand; info$auxiliary also allows the user (currently limited) some control over how the auxiliary variables are linked to the determinand data

Some variables can both be determinands to be assessed and auxiliary variables (for example, CORG or DRYWT%)
