simDAG 0.3.0

New Features

• Support for random effects and random slopes (mixed model syntax) has been added to the formula interface of node() and node_td() when using nodes of type "gaussian", "binomial" or "poisson".
• Added seven new node types: node_aftreg(), node_ahreg(), node_poreg(), node_ypreg(), node_ehreg(), node_zeroinfl() and node_mixture().

Enhancements

• Added the reference argument to rbernoulli() and rcategorical() to make it easier to specify the reference category when coding the output as a factor variable.
• +.DAG now checks whether the DAG would become cyclic when adding a node() and returns an error if it does.
• Added the include_td_nodes and include_root_nodes arguments to as.igraph.DAG().
• Changed the default of n_cores in the sim_n_datasets() function to 1 from parallel::detectCores()
• Function input to the cens_dist argument in the node_cox() function is now allowed.
• The argument as_two_cols was added to the node_cox() function to allow users to return only the time-to-event as a single column if no censoring is applied.

Bug Fixes

• Fixed a bug that occurred when a user-specified root node function returned a data.frame-like object with more than one column.
• Fixed a bug when printing the structural equation of a poisson node, in which the exp() call did not show up when the node was defined using the formula argument.

Documentation

• Added new "cookbook" vignette to showcase more possible use cases of the package.
• Visual update of the DAGs shown in the vignette figures.
