contour-methods: Methods for Function contour in Package `copula'

Description

Methods for function contour in package copula

Details

When x is of class "copula", these arguments can be supplied: fun: the function to be plotted, "dcopula" or "pcopula". n = 51: the number of points to do the plotting. theta = -30, phi = 30, expand = 0.618: arguments for "contour"

when x is of class "mvdc", these arguments are expected to replace the effect of n = 51: xlim: the range of the x variable. ylim: the range of the y variable. nx: the number of points for x to expand. ny: the number of points for y to expand.

Examples

contour(frankCopula(-0.8), dcopula)
contour(claytonCopula(2), pcopula)
x <- mvdc(gumbelCopula(3), c("norm", "norm"),
          list(list(mean = 0, sd =1), list(mean = 1)))
contour(x, dmvdc, xlim=c(-2, 2), ylim=c(-1, 3))
contour(x, pmvdc, xlim=c(-2, 2), ylim=c(-1, 3))
