surScat: Networked coincidences from a data frame.

In netCoin: Interactive Analytic Networks

Networked coincidences from a data frame.

Description

surScat produces a network object of coincidences from a data frame converting variables into dichotomies.

Usage

surScat(data, variables=names(data), active=variables, type=c("mca", "pca"), nclusters=2,
        maxN=2000, ...)

Arguments

data	a data frame.
variables	a vector of variables included in the previous data frame.
active	a vector of variables actived in the previous data frame.
type	Factorial type: mca for qualitative active variables, pca for quantitative active variables.
nclusters	number of clusters.
maxN	Maximum number or rows.
...	Any netCoin argument.

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

This function creates a netCoin object (or igraph) and, if stated, a folder in the computer with an HTML document named index.html which contains the produced graph. This file can be directly opened with your browser and sent to a web server to work properly.

Examples

# A data frame with two variables Gender and Opinion
frame<-data.frame(Gender=c(rep("Man",3),rep("Woman",3)),
                  Opinion=c("Yes","Yes","No","No","No","Yes"))
surScat(frame) # network object
