solveresid_o3_once function

Apply solveresid_o3 to a data frame and create a new column with residual ozone dose

This function allows solveresid_o3 to be added to a piped data frame. One additional column will be added to the data frame; the residual ozone dose (mg/L)

solveresid_o3_once(df, input_water = "defined_water", dose = 0, time = 0)

Arguments

• df: a data frame containing a water class column, which has already been computed using define_water_chain
• input_water: name of the column of Water class data to be used as the input for this function. Default is "defined_water".
• dose: Applied ozone dose in mg/L
• time: Ozone contact time in minutes

Returns

A data frame containing the original data frame and columns for ozone dosed, time, and ozone residual.

Details

The data input comes from a water class column, initialized in define_water or balance_ions.

For large datasets, using fn_once or fn_chain may take many minutes to run. These types of functions use the furrr package for the option to use parallel processing and speed things up. To initialize parallel processing, use plan(multisession) or plan(multicore) (depending on your operating system) prior to your piped code with the fn_once or fn_chain functions. Note, parallel processing is best used when your code block takes more than a minute to run, shorter run times will not benefit from parallel processing.

Examples

library(dplyr)
ozone_resid <- water_df %>%
  mutate(br = 50) %>%
  define_water_chain() %>%
  solveresid_o3_once(dose = 2, time = 10)

ozone_resid <- water_df %>%
  mutate(br = 50) %>%
  define_water_chain() %>%
  mutate(
    dose = seq(1, 12, 1),
    time = seq(2, 24, 2)
  ) %>%
  solveresid_o3_once()
