records_source: Create a 'records_source' Object

In admiral: ADaM in R Asset Library

Create a records_source Object

Description

The records_source object is used to find extreme records of interest.

Usage

records_source(dataset_name, filter = NULL, new_vars)

Arguments

dataset_name	The name of the source dataset The name refers to the dataset provided by the source_datasets argument of derive_param_extreme_record().
filter	An unquoted condition for selecting the observations from dataset.
new_vars	Variables to add The specified variables from the source datasets are added to the output dataset. Variables can be renamed by naming the element, i.e., ⁠new_vars = exprs(<new name> = <old name>)⁠. For example new_vars = exprs(var1, var2) adds variables var1 and var2 from to the input dataset. And new_vars = exprs(var1, new_var2 = old_var2) takes var1 and old_var2 from the source dataset and adds them to the input dataset renaming old_var2 to new_var2. Expressions can be used to create new variables (see for example new_vars argument in derive_vars_merged()). Permitted Values: list of expressions created by exprs(), e.g., exprs(ADT, desc(AVAL))

Value

An object of class records_source
