Filter and merge arguments for function calls

Simplifies the common pattern of filtering arguments from a source list to match a target function's formal parameters, then adding/overriding specific arguments.

Usage

filter_call_args(source_args, target_func, override_args = NULL)

Arguments

source_args

List of all arguments (typically from mget() or a stored args list).

target_func

Function whose formals define the filter criteria.

override_args

List of arguments to add or override (optional).

Value

List of filtered arguments ready for do.call().

Details

This function:

1. Extracts formal parameter names from target_func

2. Keeps only arguments from source_args that match those names

3. Adds or overrides with any override_args provided

Reduces boilerplate and improves readability across the codebase.
