Fetch ADaM tables from a source based on endpoint specifications

Source: R/fetch_db_data.R
fetch_db_data.Rd

This function reads the set of ADaM tables required to produce the specified endpoints from the input. It uses the user-supplied preprocessing functions specified for each endpoint to identify and process the necessary ADaM tables. It validates the preprocessing functions and applies them to the study metadata to obtain the data tables. If any preprocessing functions result in errors, the function stops and reports the errors.

Usage

fetch_db_data(study_metadata, fn_dt, env = parent.frame())

Arguments

study_metadata

Study metadata that is passed to the mk_adam* functions.

fn_dt

A data.table containing the parsed user-supplied functions.

env

Advanced parameter for specifying the evaluation environment, defaults to parent.frame().

Value

A list of ADaM tables with additional columns from fn_dt including function type, hash, name, character representation of the call, and the callable itself.
