mtkFastDesigner-class: The mtkFastDesigner class

Description

The mtkFastDesigner class is a sub-class of the class mtkDesigner. It implements the sampling method Fast and provides all the slots and methods defined in the class mtkDesigner.

Class Hierarchy

Parent classes :

mtkDesigner

Direct Known Subclasses :

Constructor

mtkFastDesigner

signature(mtkParameters = NULL, listParameters = NULL)

Slots

name:

(character) always takes the string "design".

protocol:

(character) always takes the string "R".

site:

(character) always takes the string "mtk".

service:

(character) always takes the string "Fast".

parameters:

(vector) a vector of [mtkParameter] containing the parameters to pass while calling the service.

ready:

(logical) a logical to tell if the process is ready to run.

state:

(logical) a logical to tell if the results produced by the process are available and ready to be consumed.

result:

(ANY) a data holder to hold the results produced by the process

Methods

setName

signature(this = "mtkFastDesigner", name = "character"): Not used, method inherited from the parent class.

setParameters

signature(this = "mtkFastDesigner", f = "vector"): Assigns new parameters to the process.

getParameters

signature(this = "mtkFastDesigner"): Returns the parameters as a named list.

is.ready

signature( = "mtkFastDesigner"): Tests if the process is ready to run.

setReady

signature(this = "mtkFastDesigner", switch = "logical"): Makes the process ready to run.

is.ready

signature( = "mtkFastDesigner"): Tests if the results produced by the process are available.

setReady

signature(this = "mtkFastDesigner", switch = "logical"): Marks the process as already executed.

getResult

signature(this = "mtkFastDesigner"): Returns the results produced by the process as a [mtkDesignerResult].

getData

signature(this = "mtkFastDesigner"): Returns the results produced by the process as a data.frame.

serializeOn

signature(this = "mtkFastDesigner"): Returns all data managed by the process as a named list.

run

signature(this = "mtkFastDesigner", context= "mtkExpWorkflow"): Generates the experimental design by sampling the factors.

summary

signature(object = "mtkFastDesigner"): Provides a summary of the results produced by the process.

print

signature(x = "mtkFastDesigner"): Prints a report of the results produced by the process.

plot

signature(x = "mtkFastDesigner"): Plots the results produced by the process.

report

signature(this = "mtkFastDesigner"): Reports the results produced by the process.

Examples

##			 Sensitivity analysis of the "Ishigami" model with the "Fast" method 

#	Input the factors
		data(Ishigami.factors)
		
# 	Build the processes and workflow:

#   1) the design process
		exp1.designer <- mtkFastDesigner(listParameters
	    	= list(n=1000)) 

#   2) the simulation process
		exp1.evaluator <- mtkNativeEvaluator(model="Ishigami") 

#   3) the analysis process 
		exp1.analyser <- mtkFastAnalyser()

#   4) the workflow

		exp1 <- mtkExpWorkflow(expFactors=Ishigami.factors,
	    processesVector = c(design=exp1.designer,
		evaluate=exp1.evaluator, analyze=exp1.analyser))

# 	Run the workflow and reports the results.
		run(exp1)
		print(exp1)
