Internal Helper Functions for Validation of Increments Objects

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

Usage

v_increments_relative(object)

v_increments_relative_parts(object)

v_increments_relative_dlt(object)

v_increments_dose_levels(object)

v_increments_hsr_beta(object)

v_increments_min(object)

v_increments_maxtoxprob(object)

v_increments_ordinal(object)

v_cohort_size_ordinal(object)

Arguments

object

(Increments)
object to validate.

Value

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

Functions

• v_increments_relative(): validates that the IncrementsRelative object contains valid intervals and increments parameters.

• v_increments_relative_parts(): validates that the IncrementsRelativeParts object contains valid dlt_start and clean_start parameters.

• v_increments_relative_dlt(): validates that the IncrementsRelativeDLT object contains valid intervals and increments parameters.

• v_increments_dose_levels(): validates that the IncrementsDoseLevels object contains valid levels and basis_level option.

• v_increments_hsr_beta(): validates that the IncrementsHSRBeta object contains valid probability target, threshold and shape parameters.

• v_increments_min(): validates that the IncrementsMin object contains a list with Increments objects.

• v_increments_maxtoxprob(): validates the IncrementsMaxToxProb

• v_increments_ordinal(): validates that the IncrementsOrdinal object contains valid grade and standard Increments rule.

• v_cohort_size_ordinal(): validates that the CohortSizeOrdinal object contains valid grade and standard CohortSize rule.
