simDAG 0.2.1

Enhancements

• External variables may now be used in the formula interface using eval() calls.
• Added the remove_not_at_risk argument to the sim2data() function.
• Change default of t0_sort_dag in sim_discrete_time() from TRUE to FALSE for more consistency with sim_from_dag().

Bug Fixes

• Using sim2data() with time-dependent nodes of type node_competing_events() no longer results in an unwarranted error message.
• Using the column name "time" in the time argument of long2start_stop() now works properly.

New Features

• Added the 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

• Added more examples in the formula vignette.
