plot_ND options
Created by: srcorsi-USGS
For the description of the parameter plot_ND in the plot_group_boxplots.R script, we have this:
#' @param plot_ND Logical whether or not to plot the instances when a chemical #' was not detected.
What does it actually use if plot_ND = TRUE. We can't give it a zero since we are using log scale. Is the concentration then set to the detection level, or what method is used?
