Worker function

Description

Worker function for select_parameters and select_parameters.mc

Usage

eval_parameters(
  algo,
  parameters,
  data,
  nblistw = NULL,
  standardize = TRUE,
  spconsist = FALSE,
  classidx = TRUE,
  tol,
  maxiter,
  seed = NULL,
  verbose = TRUE
)

Arguments

algo

A string indicating which method to use (FCM, GFCM, SFCM, SGFCM)

parameters

A dataframe of parameters with columns k,m and alpha

data

A dataframe with numeric columns

nblistw

A list.w object describing the neighbours typically produced by the spdep package

standardize

A boolean to specify if the variable must be centered and reduce (default = True)

spconsist

A boolean indicating if the spatial consistency must be calculated

classidx

A boolean indicating if the quality of classification indices must be calculated

tol

The tolerance criterion used in the evaluateMatrices function for convergence assessment

maxiter

An integer for the maximum number of iteration

seed

An integer used for random number generation. It ensures that the start centers will be the same if the same integer is selected.

verbose

A boolean indicating if a progressbar should be displayed

Value

a DataFrame containing for each combinations of parameters several clustering quality indexes.
