Description

init.assessment creates S4 assessment from dependencies data.frame, including decisions, stakeholders, probabilities, and variables.

NOTE! You must include the formula code from each variable page, otherwise formulas and dependencies are not updated.

Parameters

Dependencies

• A data.frame that has the structure of oassessment@name (Columns: Name, Identifier, Direction, Result)
