Unnest over user-supplied functions in endpoint definitions

Source: R/unnest_endpoint_functions.R
unnest_endpoint_functions.Rd

This function processes a data.table containing endpoint definitions by unnesting the function calls in specified columns. It is tailored for endpoint definition specific data structure, where endpoint definitions include user-supplied functions. After unnesting, it removes any rows where the function is NULL (indicating an empty function) and computes a hash for each function call for identification purposes.

Usage

unnest_endpoint_functions(
  endpoint_defs,
  fn_cols = c("data_prepare", "stat_by_strata_by_trt", "stat_by_strata_across_trt",
    "stat_across_strata_across_trt", "crit_endpoint", "crit_by_strata_by_trt",
    "crit_by_strata_across_trt"),
  env = parent.frame()
)

Arguments

endpoint_defs

A data.table containing endpoint definitions with nested function calls in the columns defined by the fn_cols argument.

fn_cols

A character vector with default names of the columns that contain the function calls. These columns are expected to be in the endpoint_defs data.table.

env

The environment from which to evaluate the functions. The default is the parent frame from which the function is called.

Value

A data.table with each function call represented as a separate row, including a unique hash for each function call.
