Helper function that calculates excess and population hazards for a given transition

A function that calculates the excess and population hazards for a given transition. Code is based on function rs.surv from the relsurv package.

Usage

haz_function(
  formula = formula(data),
  data,
  ratetable = relsurv::slopop,
  na.action,
  add.times,
  rmap,
  include.all.times = FALSE
)

formula: A non-parametric Surv-based formula, e.g. Surv(times, status)~1
data: A subset of the msprep object (dataset) where there's only data for the chosen transition
ratetable: A table of event rates, organized as a ratetable object, such as slopop
na.action: A missing-data filter function, applied to the model.frame, after any subset argument has been used. Default is options()$na.action
add.times: Additional times at which the hazards should be evaluated
rmap: An optional list to be used if the variables are not organized and named in the same way as in the ratetable object
include.all.times: Should hazards be evaluated at all times in seq(minimum time, maximum time, by=1). Default is FALSE

A list containing the needed hazards.
