sch_xy_gantt_matrix: XY Gantt Matrix
In rubens2005/criticalpath: An Implementation of the Critical Path Method

Description Usage Arguments Value See Also Examples

Transform a Gantt matrix into x, y coordinates and the weight one. Each point greater than zero in a Gantt matrix becomes a x, y coordinate. Atention: the schedule must be planned with the function sch_plan().

1	sch_xy_gantt_matrix(sch, gantt = NULL)

`sch`	A schedule object.
`gantt`	A Gantt Matrix. If it is not informed, it will use `gantt_matrix()` before this function.

A matrix with three columns: x, y and weight.
