plot_lead: Create dissolved lead and DIC contour plot given input data frame

Description

This function takes a data frame and outputs a contour plot of dissolved lead and DIC plot. Assumes that the range of pH and dissolved inorganic carbon (DIC) occurs at a single temperature and TDS.

Usage

plot_lead(df, temp, tds, ph_range, dic_range)

Value

A ggplot object displaying a contour plot of dissolved lead, pH, and DIC

Arguments

df

Source data as a data frame. Must have pH and DIC columns. Columns containing a single temperature and TDS can also be included.

temp

Temperature used to calculate dissolved lead concentrations. Defaults to a column in df.

tds

Total dissolved solids used to calculate dissolved lead concentrations. Defaults to a column in df.

ph_range

Optional argument to modify the plotted pH range. Input as c(minimum pH, maximum pH).

dic_range

Optional argument to modify the plotted DIC range. Input as c(minimum DIC, maximum DIC).

Examples

# \donttest{
historical <- data.frame(
  ph = c(7.7, 7.86, 8.31, 7.58, 7.9, 8.06, 7.95, 8.02, 7.93, 7.61),
  dic = c(
    14.86, 16.41, 16.48, 16.63, 16.86, 16.94, 17.05, 17.23,
    17.33, 17.34
  ),
  temp = 25,
  tds = 200
)
