setProcess-methods: The setProcess method

Description

Places or replaces a process into the workflow.

Usage

setProcess(this, p, name)

Arguments

this

the underlying object of the class mtkExpWorkflow.

p

an object of the class mtkProcess.

name

a string from "design", "evaluate", or "analyze" to specify the process to place or replace.

Value

Details

This method is especially useful when we need to compare different methods or models.

# Re-analyzes the model "Ishigami" with the method "Morris"

#	1) Build a designer with the method "Morris" and put it into the workflow
	morris.designer <- mtkNativeDesigner(

		information=list(r=20,type="oat",levels=4,grid.jump=2)
		) 
	setProcess(ishiReg, morris.designer, "design")
	
#	2) Build an analysis process with the default method and put it
#     into the workflow
		default.analyser <- mtkDefaultAnalyser()
		setProcess(ishiReg, default.analyser, "analyze")
#	3) Run the new workflow

	run(ishiReg)
