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
Enhancements
output argument to the
rbernoulli() function to allow different output
formats.sort_dag in
sim_from_dag() from TRUE to
FALSE.coerce2factor and
coerce2numeric arguments in rcategorical(),
node_multinomial() and node_binomial() to the
output argument for a more consistent syntax and easier
usage.type argument in node() and
node_td().layout function in
plot.DAG() is now supported.Bug Fixes
node_fill argument of the plot.DAG()
function is no longer being ignored if mark_td_nodes was
set to TRUE.New Features
formula argument. Standard
formulas (without betas and intercepts) are still supported, but no
longer mentioned in the documentation and will be deprecated in future
versions.Documentation
node() function works.Enhancements
eval() calls.remove_not_at_risk argument to the
sim2data() function.t0_sort_dag in
sim_discrete_time() from TRUE to
FALSE for more consistency with
sim_from_dag().Bug Fixes
sim2data() with time-dependent nodes of type
node_competing_events() no longer results in an unwarranted
error message."time" in the time
argument of long2start_stop() now works properly.New Features
node_identity() function to allow users to
directly calculate nodes as an R expression of other nodes without the
need to define a new function.Documentation
Bug Fixes
print.DAG()data.tableNew Features
formula interface of
node() and node_td() when using nodes of type
"gaussian", "binomial" or
"poisson".node_aftreg(),
node_ahreg(), node_poreg(),
node_ypreg(), node_ehreg(),
node_zeroinfl() and node_mixture().Enhancements
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.include_td_nodes and
include_root_nodes arguments to
as.igraph.DAG().n_cores in the
sim_n_datasets() function to 1 from
parallel::detectCores()cens_dist argument in the
node_cox() function is now allowed.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
data.frame-like object with more than one
column.exp() call did not show up when the node was
defined using the formula argument.Documentation
