define_water_once {tidywater} | R Documentation |
Apply define_water
and output a dataframe
Description
This function allows define_water
to be added to a piped data frame.
It outputs all carbonate calculations and other parameters in a data frame.
tidywater functions cannot be added after this function because they require a water
class input.
Usage
define_water_once(df)
Arguments
df |
a data frame containing columns with all the parameters listed in |
Details
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.
Value
A data frame containing columns that were filled or calculated based on define_water.
