Internal Helper Functions for Validation of GeneralData Objects

Description

These functions are only used internally to validate the format of an input GeneralData or inherited classes and therefore not exported.

Usage

v_general_data(object)

h_doses_unique_per_cohort(dose, cohort)

v_data(object)

v_data_dual(object)

v_data_parts(object)

v_data_mixture(object)

v_data_da(object)

v_data_ordinal(object)

v_data_grouped(object)

Arguments

object	(GeneralData) object to validate.
dose	(numeric) dose values.
cohort	(integer) cohort indices parallel to doses.

Value

A character vector with the validation failure messages, or TRUE in case validation passes.

TRUE if dose is unique per cohort, otherwise FALSE.

Functions

• v_general_data(): validates that the GeneralData object contains unique ID, non-negative cohort indices and ID and cohort vectors are of the same length nObs.

• h_doses_unique_per_cohort(): helper function which verifies whether the dose values are unique in each and every different cohort.

• v_data(): validates that the Data object contains valid elements with respect to their types, dependency and length.

• v_data_dual(): validates that the DataDual object contains valid biomarker vector with respect to its type and the length.

• v_data_parts(): validates that the DataParts object contains valid elements with respect to their types, dependency and length.

• v_data_mixture(): validates that the DataMixture object contains valid elements with respect to their types, dependency and length.

• v_data_da(): validates that the DataDA object contains valid elements with respect to their types, dependency and length.

• v_data_ordinal(): validates that the DataOrdinal object contains valid elements with respect to their types, dependency and length.

• v_data_grouped(): validates that the DataGrouped object contains valid group information.
