New Features

  • Added the link argument to node_gaussian(), node_binomial(), node_poisson(), node_negative_binomial() and node_zeroinfl() to allow different link functions when generating data from these nodes.
  • Added the as.dagitty.DAG() function to allow direct conversion of DAG objects to dagitty objects.

Bug Fixes

  • Previously, the sim_n_datasets() function used stats::runif(1) as a default for the seed argument. Because seeds are coerced to integers in set.seed(), this essentially meant the seed argument was always set to 0 (unless changed by the user), which was not intended. We changed the default to be NULL, which is equivalent to not setting a seed. This might change results obtained using previous versions. To get the same result as in previous versions, use seed=0 or seed=stats::runif(1).
  • Fixed a bug that occurred when calling node() or node_td() inside a function with objects passed to parents or formula.

Documentation

  • Added explanations for how to simulate data for Cox models with time-varying covariates and Aalen additive hazards models with time-varying covariates to the cookbook vignette.
