Examples

  ## Not run: ###dontrunbegin

  # create input data
  adata <- artificial.data(rnd_features = 10)
  showme(adata)
  
  # Parametrize and run MCFS-ID procedure
  result <- mcfs(class~., adata, cutoffPermutations = 0, featureFreq = 10,
                  finalCV = FALSE, finalRuleset = FALSE, threadsNumber = 2)

  head(prune.data(adata, result, size = result$cutoff_value))
