52_cmv_plotting_functions: Plots of Continuous Multivariate Models

In probhat: Multivariate Generalized Kernel Smoothing and Related Statistical Methods

Description

Plots of bivariate and trivariate continuous probability distributions.

Usage

#calls barsurf::plot_cfield or barsurf::plot_surface
plot_cpd_bv (sf, in3d=FALSE, data, ..., n=30,
    main, xlab, ylab, zlab,
    xlim, ylim, zlim,
    add=FALSE, point.color)

#calls barsurf::plot_cfield_3d
plot_cpd_tv (sf, iso=FALSE, ...,
    main, xlab, ylab, zlab,
    xlim, ylim, zlim,
    z.reverse=FALSE)

Arguments

sf	A suitable function object. Here, this is a continuous multivariate probability distribution, with two or three random variables. Refer to the references and see also sections.
in3d	Logical, if true, produce a 3D plot.
iso	Logical, if true, produce an isosurface plot.
data	Logical, if true, plot data points. Ignored, if in3d or add is true, or sf is a conditional distribution. Defaults to true, if the number of observations is not more than 2000.
main, xlab, ylab, zlab	Optional strings, main/axes titles. Note that these depend on the barsurf package.
xlim, ylim, zlim	Optional length-2 numeric vectors, giving the plot ranges.
z.reverse	Logical, if true, reverse the z axis. Ignored, if zlim supplied.
n	Numeric vector of length one or two, giving the number of grid points in each direction.
add	Logical, if true, add to a previous plot. Ignored, in 3d case.
point.color	String, the (data) point color.
...	Other arguments for barsurf functions, refer to details.

Details

These functions call barsurf::plot_cfield, barsurf::plot_surface, barsurf::plotf_cfield_3d and barsurf::plotf_isosurface.

There are some private intermediate functions, that change some of the defaults.
Note that by default, more detail is used in bivariate CDFs than bivariate PDFs.
