Enhancements
node() and node_td() now support character
vectors in the ‘name’ argument, allowing easy creation of multiple nodes
with the same definitionBug Fixes
node_time_to_event() function
that lead to the immunity_duration parameter being used
incorrectly. Since events were still recorded correctly, this was only
apparent when using save_states="all". Works correctly
now.dag2matrix() if the dag object
contained only root nodes. In this case, a logical matrix was returned.
Now it returns the correct numeric matrix.New Features
sim_n_datasets() function to generate
multiple datasets from a single dag object, possibly using multicore
processingDocumentation
General
simDAG no longer lists data.table under
“Depends” in the description file. It is instead listed under “Imports”
as recommended by the data.table crewEnhancements
summary.DAG()
and summary.DAG.node()overlap argument to both
long2start_stop() and sim2data() to directly
create start-stop data with overlapping durations, as needed for some
statistical modelstarget_event and keep_only_first
arguments to sim2data() and related functions, to allow
direct transformation into model-ready datasetlong2start_stop() function more
computationally efficientBug Fixes
node_time_to_event() function, which printed an error when
not all arguments to prob_fun were supplied, even when
these arguments had default valuesprint.DAG.node() which occurred when a
time-to-event node with no parents was suppliedsim2data() which lead to inconsistent
results when event_duration=0 was used in one or more nodes
of type “time_to_event” or “competing_events”. This made me realize that
event durations smaller than 1 make no sense. They are now no longer
allowed and the default of the node types has been changed
accordingly.formula objects of child nodesNew Features
as.igraph.DAG() method which extends the
generic function as.igraph() to conveniently parse
DAG objects to igraph objectsas.data.table.simDT() and
as.data.frame.simDT() for user convenienceDocumentation
