This example \nuses tidywater base functions to model a single water quality scenario.\n\n```{r example, message = FALSE, setup = TRUE}\nlibrary(tidywater)\nlibrary(tidyverse)\n## Use base tidywater functions to model water quality for a single scenario.\nbase_coagulation \u003c- define_water(ph = 8, alk = 90, tds = 50, toc = 3, doc = 2.8, uv254 = 0.08) %\u003e%\n  # note that we get a warning about sulfate from this code because we didn't specify sulfate in the define_water\n  chemdose_ph(alum = 30) %\u003e%\n  chemdose_toc(alum = 30)\n```\n\nTo model multiple water quality scenarios, use tidywater's helper functions (x_df) to \napply the models to a dataframe. The `pluck_cols` argument can be added to return the parameters impacted by the model\nas separate columns. The `pluck_water` function can pull any parameter from a water into a separate column.\n\n```{r}\n\ncoagulation \u003c- water_df %\u003e%\n  define_water_df(output_water = \"raw\") %\u003e%\n  mutate(alum = 30) %\u003e%\n  chemdose_ph_df(input_water = \"raw\", output_water = \"phchange\") %\u003e% # return \"phchange\" water\n  chemdose_toc_df(input_water = \"phchange\", output_water = \"coag\", pluck_cols = TRUE) # return \"coag\" water and coag_doc, coag_toc, coag_uv254 as columns\n\n## To get individual parameters, use `pluck_water`\ncoagulation \u003c- coagulation %\u003e%\n  pluck_water(input_waters = c(\"raw\", \"coag\"), parameter = c(\"ph\", \"doc\"))\n```\n\nNote that these functions use a \"water\" class. The \"water\" class is the foundation of the package; \nit provides a mechanism for linking models in any order while maintaining water quality information.\nThe `define_water` function takes water quality inputs, but `define_water_df` may be used to convert\na dataframe to a list of \"waters\".\n\nFor more detailed examples on tidywater functions and how to use \"water\" class data, please see \nthe tidywater vignettes: `browseVignettes(\"tidywater\")`\n\n## Limitations\nThis project is maintained by volunteers and is provided without warranties or guarantees of any kind.  \n\nUse at your own risk.
