mtkSobolAnalyser-class: The mtkSobolAnalyser class

Description

The mtkSobolAnalyser class is a sub-class of the class mtkAnalyser. It implements the sensitivity analysis method Sobol and provides all the slots and methods defined in the class mtkAnalyser.

Direct Known Subclasses :

Constructor

mtkSobolAnalyser

signature(mtkParameters = NULL, listParameters = NULL)

Slots

name:

(character) always takes the string "analyze".

protocol:

(character) always takes the string "R".

site:

(character) always takes the string "mtk".

service:

(character) always takes the string "Sobol".

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 = "mtkSobolAnalyser", name = "character"): Not used, method inherited from the parent class.

setParameters

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

getParameters

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

is.ready

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

setReady

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

is.ready

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

setReady

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

getResult

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

getData

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

serializeOn

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

run

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

summary

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

print

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

plot

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

report

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