perspective.grid {GRIDCOPULA}

Draws the density / distribution function of a grid copula with perspective

Description

Draws the density / distribution function of a grid copula with perspective

Usage

perspective.grid(
  gc,
  FUN = "d.grid",
  u1 = seq(0, 1, length.out = 21),
  u2 = seq(0, 1, length.out = 21),
  ang.theta = -30,
  ang.phi = 25,
  distancia = 10
)

Arguments

gc

a grid type copula object.

FUN

the name of the function to be applied (d.grid, p.grid), default is 'd.grid'.

u1

indicates the place for lines on axis u_1.

u2

indicates the place for lines on axis u_2.

ang.theta

angle for the azimuthal direction.

ang.phi

angle for the colatitude.

distancia

the distance of the eyepoint from the centre of the box.

Value

Returns a graph of the density / distribution.

Examples

n <- 500
x <- rgamma(n,4,1/2)
e <- rnorm(n,0,.3)
y <- sin(x+e)
Fx <- ecdf(x)
Fy <- ecdf(y)
u <- Fx(x)
v <- Fy(y)
df <- cbind(u,v)
k <- 10
m <- 10
copula.grid <- estimate.gridCopula(U = df, k = k, m = m , method = "ml")
perspective.grid(gc = copula.grid, ang.theta = 90 , ang.phi = 80, distancia = 3)
perspective.grid(gc = copula.grid, FUN = "p.grid")

#Iris 
copula.grid <- estimate.gridCopula(X = iris[,1:2], k = k, m = m , method = "ml")
perspective.grid(gc = copula.grid, ang.theta = 90 , ang.phi = 80, distancia = 3)
