netCorr.Rd
netCorr
produces a network object of correlations. Its input has to be at least one set of quantitative variables.
netCorr(variables, weight=NULL, pairwise=FALSE, minimum=-Inf, maximum=Inf, sort=FALSE, decreasing=TRUE, frequency=FALSE, means=TRUE, method="pearson", criteria="p", Bonferroni=FALSE, minL=0, maxL=Inf, sortL=NULL, decreasingL=TRUE, igraph=FALSE, ...)
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. |
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.
