construct a survival object from tabular specification

Usage

construct_part_surv_tib(surv_def, ref, state_names, env = new.env())

Arguments

surv_def: a data frame with the specification. See details.
ref: data frame with information about the fits.
state_names: names of the model states
env: an environment

Value

a list with one element for each strategy. Each element is in turn a part_surv object, a list with two elements, pfs and os. And those elements are survival objects of various kinds, with the commonality that they can be used in compute_surv().

Details

This function is meant to be used only from within tabular_input.R. It won't work well otherwise, in that the environment is unlikely to have what you need.

columns of surv_def: .strategy, .type, .subset, dist, until where dist can be either the name of a distribution along with parameters, or a reference to a fit for example: fit('exp') or exp(rate = 0.5)
