netCorr: Networked correlations.

In netCoin: Interactive Analytic Networks

Networked correlations.

Description

netCorr produces a network object of correlations. Its input has to be at least one set of quantitative variables.

Usage

netCorr(variables, weight=NULL, pairwise=FALSE,
        minimum=-Inf, maximum=Inf, sort=FALSE, decreasing=TRUE,
        frequency=FALSE, means=TRUE, 
        method=c("pearson", "kendall", "spearman"), 
        criteria="p", Bonferroni=FALSE, minL=0, maxL=Inf,
        sortL=NULL, decreasingL=TRUE,
        igraph=FALSE, ...)

Arguments

variables	a data frame with at least two quantitative variables.
weight	a vector of weights. Optimal for data.framed tables
pairwise	Pairwise mode of handling missing values if TRUE. Listwise by default.
minimum	minimum frequency to be considered
maximum	maximum frequency to be considered
sort	sort the correlation matrix according to the frequency of the events
decreasing	decreasing or increasing sort of the matrix
frequency	a logical value true if frequencies are to be shown. Default=FALSE.
means	a logical value true if means are to be shown. Default=TRUE.
method	a vector of statistics of similarity. Pearson correlation by default. spearman and kendall are also possible
criteria	statistic to be use for selection criteria.
Bonferroni	Bonferroni criterium of the signification test.
minL	minimum value of the statistic to include the edge in the list.
maxL	maximum value of the statistic to include the edge in the list.
sortL	sort the list according to the values of a statistic. See below
decreasingL	order in a decreasing way.
igraph	Produces an igraph object instead of a netCoin object if TRUE
...	Any netCoin argument.

Value

The function creates a netCoin object and eventually 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.
