logCoin: Networked log-linear models.

In netCoin: Interactive Analytic Networks

Networked log-linear models.

Description

logCoin produces a network object from loglinear models parameters.

Usage

logCoin(data, variables=names(data), exogenous=NULL, noFirstCat= NULL,
        weight=NULL, order= 2, pairwise=FALSE, twotails = FALSE,
        pmax = 0.05, frequency = FALSE, percentage = FALSE, 
        directed=FALSE, igraph=FALSE, ...)

Arguments

data	a data frame.
variables	a vector of names of variables included in the previous data frame.
exogenous	a vector of names of variables whose relations amongst them are of no interest. None by default.
noFirstCat	a vector of names of dichotomous variables to appear without the category (no characteristic).
weight	a vector of weights. Optimal for dataframed tables.
order	maximum order parameters to be included in the loglinear model (default=2)
pairwise	Pairwise mode of handling missing values if TRUE. Listwise by default.
twotails	Application of twotail tests to the parameters (default: FALSE, i.e., onetail)
pmax	maximum value of the statistic to include the edge in the list. By default is 0.05, but 0.5 is recommended if data has not been sampled.
frequency	a logical value true if frequencies are to be shown. Default=FALSE.
percentage	a logical value true if percentages are to be shown. Default=TRUE.
directed	includes arrows to the links (target would be the categories of first mention variables).
igraph	Produces an igraph object instead of a netCoin object if TRUE.
...	Any netCoin argument.

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 n=1,000 sample from the European Social Survey.(Round 8, 2016)
data("ess")
logCoin(ess, c("Social participation", "Political participation"), 
  noFirstCat=c("Social participation", "Political participation"),  
  exogenous=c("Age", "Gender"),  weight = "cweight", 
  order=3, pmax=.05,percentage = TRUE, frequency = TRUE ) # network object
