checkem: First Gate Function

In monoClust: Perform Monothetic Clustering with Extensions to Circular Data

Description

This function checks what are available nodes to split and then call find_split() on each node, then decide which node creates best split, and call splitter() to perform the split.

Usage

checkem(
  data,
  cuts,
  frame,
  cloc,
  dist,
  variables,
  minsplit,
  minbucket,
  split_order,
  ncores
)

Arguments

data	Original data set.
cuts	Cuts data set, which has the next higher value of each variable in the original data set.
frame	The split tree transferred as data frame.
cloc	Vector of current cluster membership.
dist	Distance matrix of all observations in the data. exported function yet. Vector of 1 for all observations.
variables	List of variables selected for clustering procedure. It could be a vector of variable indexes, or a vector of variable names.
minsplit	The minimum number of observations that must exist in a node in order for a split to be attempted.
minbucket	The minimum number of observations in any terminal leaf node. Default is minsplit/3.
split_order	The control argument to see how many split has been done.
ncores	Number of CPU cores on the current host.

Value

It is not supposed to return anything because global environment was used. However, if there is nothing left to split, it returns 0 to tell the caller to stop running the loop.
