This function plucks one or more selected parameters from selected columns of water class objects. The names of the output columns will follow the form water_parameter To view all slots as columns, please use one of the fn_once functions or convert_water.

pluck_water(df, input_waters = c("defined_water"), parameter)

Arguments

• df: a data frame containing a water class column, which has already been computed using define_water
• input_waters: vector of names of the columns of water class data to be used as the input for this function.
• parameter: vector of water class parameters to view outside the water column

Returns

A data frame containing columns of selected parameters from a list of water class objects.

Examples

library(dplyr)
library(furrr)
library(purrr)
library(tidyr)

pluck_example <- water_df %>%
  define_water_chain() %>%
  pluck_water(parameter = "tot_co3")

pluck_example <- water_df %>%
  define_water_chain() %>%
  balance_ions_chain() %>%
  pluck_water(input_waters = c("defined_water", "balanced_water"), parameter = c("na", "cl"))

plan(multisession, workers = 2) # Remove the workers argument to use all available compute
pluck_example <- water_df %>%
  define_water_chain() %>%
  pluck_water(parameter = c("ph", "alk"))

# Optional: explicitly close multisession processing
plan(sequential)
