dag.plot: DAG plot

Description

This function plots a directed acyclic graph (DAG).

Usage

dag.plot(
  prec1and2 = matrix(0),
  prec3and4 = matrix(0),
  critical.activities = NULL
)

Value

A plot.

Arguments

prec1and2

A matrix indicating the order of precedence type 1 and 2 between the activities (Default=matrix(0)). If value \((i,j)=1\) then activity \(i\) precedes type \(1\) to \(j\), and if \((i,j)=2\) then activity \(i\) precedes type \(2\) to \(j\). Cycles cannot exist in a project, i.e. if an activity \(i\) precedes \(j\) then \(j\) cannot precede \(i\).

prec3and4

A matrix indicating the order of precedence type 3 and 4 between the activities (Default=matrix(0)). If value \((i,j)=3\) then activity \(i\) precedes type \(3\) to \(j\), and if \((i,j)=4\) then activity \(i\) precedes type \(4\) to \(j\). Cycles cannot exist in a project, i.e. if an activity \(i\) precedes \(j\) then \(j\) cannot precede \(i\).

critical.activities

A vector indicating the critical activities to represent them in a different color (Default=NULL) .

Examples

prec1and2<-matrix(c(0,1,0,2,0,0,0,0,0,1,0,0,0,1,0,0,0,0,0,0,0,0,0,2,0),nrow=5,ncol=5,byrow=TRUE)
prec3and4<-matrix(0,nrow=5,ncol=5)
prec3and4[3,1]<-3
dag.plot(prec1and2,prec3and4)
