Load Scalar from JSON

Description

Load a scalar from json

This function is intended for advanced use cases in which users require detailed control of sampling algorithms and data structures. Minimal input validation and error checks are performed – users are responsible for providing the correct inputs. For tutorials on the "proper" usage of the stochtree's advanced workflow, we provide several vignettes at https://stochtree.ai/

Usage

loadScalarJson(json_object, json_scalar_label, subfolder_name = NULL)

Arguments

json_object	Object of class CppJson
json_scalar_label	Label referring to a particular scalar / string value (i.e. "num_samples") in the overall json hierarchy
subfolder_name	(Optional) Name of the subfolder / hierarchy under which vector sits

Value

R vector

Examples

example_scalar <- 5.4
example_json <- createCppJson()
example_json$add_scalar("myscalar", example_scalar)
roundtrip_scalar <- loadScalarJson(example_json, "myscalar")
