cloud2-methods: Cloud Plot Methods ('cloud2') in Package 'copula'

Description

Function and Methods cloud2() to draw (lattice) cloud plots of two-dimensional distributions from package copula.

Usage

# S4 method for matrix
cloud2(x,
      xlim = range(x[,1], finite = TRUE),
      ylim = range(x[,2], finite = TRUE),
      zlim = range(x[,3], finite = TRUE),
      xlab = NULL, ylab = NULL, zlab = NULL,
      scales = list(arrows = FALSE, col = "black"),
      par.settings = standard.theme(color = FALSE), ...)
# S4 method for data.frame
cloud2(x,
      xlim = range(x[,1], finite = TRUE),
      ylim = range(x[,2], finite = TRUE),
      zlim = range(x[,3], finite = TRUE),
      xlab = NULL, ylab = NULL, zlab = NULL,
      scales = list(arrows = FALSE, col = "black"),
      par.settings = standard.theme(color = FALSE), ...)
# S4 method for Copula
cloud2(x, n,
      xlim = 0:1, ylim = 0:1, zlim = 0:1,
      xlab = quote(U[1]), ylab = quote(U[2]), zlab = quote(U[3]), ...)
# S4 method for mvdc
cloud2(x, n,
      xlim = NULL, ylim = NULL, zlim = NULL,
      xlab = quote(X[1]), ylab = quote(X[2]), zlab = quote(X[3]), ...)

Value

An object of class “trellis” as returned by cloud().

Arguments

x: a "matrix", "data.frame", "Copula" or a "mvdc" object.
xlim, ylim, zlim: the x-, y- and z-axis limits.
xlab, ylab, zlab: the x-, y- and z-axis labels.
scales: a list determining how the axes are drawn; see cloud().
par.settings: see cloud().
n: when x is not matrix-like: The sample size of the random sample drawn from x.
...: additional arguments passed to the underlying cloud().

Methods

Cloud plots for objects of class "matrix" , "data.frame", "Copula" or "mvdc".

Examples

Run this code

## For 'matrix' objects
cop <- gumbelCopula(2, dim = 3)
n <- 1000
set.seed(271)
U <- rCopula(n, copula = cop)
cloud2(U, xlab = quote(U[1]), ylab = quote(U[2]), zlab = quote(U[3]))

## For 'Copula' objects
set.seed(271)
cloud2(cop, n = n) # same as above

## For 'mvdc' objects
mvNN <- mvdc(cop, c("norm", "norm", "exp"),
             list(list(mean = 0, sd = 1), list(mean = 1), list(rate = 2)))
cloud2(mvNN, n = n)
