Edge list.

Description

Convert a coincidence/similarity/distance matrix into an edge list form.

Usage

edgeList(data, procedures="Haberman", 
         criteria="Z", level=.95, Bonferroni=FALSE, 
         min=-Inf, max=Inf, support=-Inf, directed=FALSE, 
         diagonal=FALSE, sort=NULL, decreasing=TRUE, pairwise=FALSE)

Arguments

data	a coin object, let's say an R matrix with frequencies and an attribute (n) giving the number of scenarios. In case of change of shape, data should be a matrix.
procedures	a vector of statistics of similarity. See below.
criteria	statistic to be use for selection criteria.
level	confidence level
Bonferroni	Bonferroni criterium of the signification test.
min	minimum value of the statistic to include the edge in the list.
max	maximum value of the statistic to include the edge in the list.
support	minimum value of the frequency of the coincidence to be edged
directed	includes same edges only once.
diagonal	includes auto-links
sort	sort the list according to the values of a statistic. See below
decreasing	order in a decreasing way.
pairwise	Pairwise mode of handling missing values if TRUE. Listwise by default.

Details

Possible measures in procedures are

• Frequencies (f), Relative frequencies (x), Conditional frequencies (i), Coincidence degree (cc), Probable degree (cp),

• Expected (e), Confidence interval (con)

• Matching (m), Rogers & Tanimoto (t), Gower (g), Sneath (s), Anderberg (and),

• Jaccard (j), Dice (d), antiDice (a), Ochiai (o), Kulczynski (k),

• Hamann (ham), Yule (y), Pearson (p), odds ratio (od), Rusell (r),

• Haberman (h), Z value of Haberman (z),

• Hypergeometric p greater value (hyp).

• Convert a matrix into an edge list (shape).

Value

A data frame in which the two first columns are source and target. The rest of the columns are the different statistics explicited in funcs parameter.
