anfis.plotmf {FuzzyR}

Plot membership functions for an ANFIS object

Description

Plots a 2D graph of all membership functions from the specified variable which must be part of an anfis object.

Usage

anfis.plotmf(
  anfis,
  varType,
  varIndex,
  xx = NULL,
  timelimit = 0,
  xlab = NULL,
  ylab = NULL,
  main = NULL
)

Arguments

anfis

Requires an existing anfis as an argument.

varType

Can be either 'input' or 'output', representing the type of variable.

varIndex

A numerical integer, representing the index of the input or output variable whose membership functions shall be plotted (base 1).

xx

primary inputs for extra lines

timelimit

for perturbation

xlab

X axis label using font, size and color

ylab

Y axis label, same font attributes as xlab

main

The main title (on top)

Value

A two dimensional graph displaying all the membership functions of a given variable.

Examples

fis <- anfis.tipper()
anfis <- anfis.builder(fis)
data.num <- 5
input.num <- length(fis$input)
input.stack <- matrix(rnorm(data.num*input.num), ncol=input.num)
y <- matrix(rnorm(data.num))
data.trn <- cbind(input.stack, y)
anfis.eval(anfis, input.stack)
anfis.final <- anfis.optimise(anfis, data.trn, epoch.total=500,
                                 stepsize=0.01, rate.inc=1.1, rate.dec=0.9)
anfis.plotmf(anfis, 'input', 1)
anfis.plotmf(anfis.final, 'input', 1)
