pairs2: Scatter-Plot Matrix ('pairs') for Copula Distributions with Nice Defaults

Description

A version of graphics' package pairs(), particularly useful for visualizing dependence in multivariate (copula) data.

Usage

pairs2(x, labels = NULL, labels.null.lab = "U", …)

Arguments

x

a numeric matrix or an R object for which as.matrix(x) returns such a matrix.

labels

the variable names, typically unspecified.

labels.null.lab

the character string determining the “base name” of the variable labels in case labels is NULL and x does not have all column names given.

…

further arguments, passed to pairs().

Examples

# NOT RUN {
## Create a 100 x 7 matrix of random variates from a t distribution
## with four degrees of freedom and plot the generated data
U <- matrix(rt(700, df = 4), ncol = 7)
pairs2(U, pch = ".")
# }
