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 signature '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 signature '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 signature '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 signature 'mvdc'
cloud2(x, n,
      xlim = NULL, ylim = NULL, zlim = NULL,
      xlab = quote(X[1]), ylab = quote(X[2]), zlab = quote(X[3]), ...)

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().

Value

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

Methods

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

Examples

## 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)
