bb3D: Buys-Ballot 3D plot

Description

Draw perspective plot of surface over the month-year plane.

Usage

bb3D (MR, s, t0, color, x, y)

Arguments

MR

a matrix containing the values to be plotted (NAs are allowed).

s

periodicity of the series.

t0

a vector of two elements indicating the year and season of the first observation.

color

logical. If TRUE a coloured graphic is showed. Otherwise, grey scale.

x, y

angles defining the viewing direction. x gives the azimuthal direction and y the colatitude.

Value

• Perspective graphic of the surface over the month-year plane.

Details

MR is a matrix with the data of the series defined as the matrix provided by quarterg in quarterly series and bbmp in monthly series.

When the graphic is showed a window is launched as well. Coordinates of the mouse inside this window represent angles defining the viewing direction. The graphic rotates clicking on it with the right button of the mouse.
