Description

from calculated stability based on Rand indexes for consecutive clustering run, find the resolution (window), where the stability is the highest

Usage

1
2
find_optimal_stability(list_clusters, run_RandIdx, bagging = FALSE,
  windows = seq(from = 0.025, to = 1, by = 0.025))

Arguments

list_clusters

is a list object containing 40 clustering results

run_RandIdx

is a data frame object from iterative clustering runs

bagging

is a logical that is true if bagging is to be performed, changes return

windows

a numeric vector specifying the ranges of each window.

Value

bagging == FALSE => a list with optimal stability, cluster count and summary stats bagging == TRUE => a list with high res cluster count, optimal cluster count and keystats
