Retrieve endpoint information from the chyaml field of a chent object

R6 class objects of class chent represent chemical entities and can hold a list of information loaded from a chemical yaml file in their chyaml field. Such information is extracted and optionally aggregated by this function.

Arguments

Arguments

>>>>>>> refs/remotes/origin/main

chent: The chent object to get the information from
medium: The medium for which information is sought
type: The information type
lab_field: If not NA, do we want laboratory or field endpoints
redox: If not NA, are we looking for aerobic or anaerobic data
value: The name of the value we want. The list given in the =======; The name of the value we want. The list given in the >>>>>>> refs/remotes/origin/main usage section is not exclusive
aggregator: The aggregator function. Can be mean, =======; The aggregator function. Can be mean, >>>>>>> refs/remotes/origin/main geomean, or identity, for example.
raw: Should the number(s) be returned as stored in the chent object (could be a character value) to retain original information about precision?
signif: How many significant digits do we want
values: The values to be returned
aggregators: A named vector of aggregator functions to be used

<<<<<<< HEAD

Value

The result from applying the aggregator function to the values converted to a numeric vector, rounded to the given number of significant digits, or, if raw = TRUE, the values as a character value, retaining any implicit information on precision that may be present.

The functions soil_* are functions to extract soil specific endpoints. For the Freundlich exponent, the capital letter N is used in order to facilitate dealing with such data in R. In pesticide fate modelling, this exponent is often called 1/n.
