bivariateNormal

Plot the bivariate normal density using wireframe for specified rho.

Description

Plot the bivariate normal density using wireframe for specified rho. There is a shiny app that allows this to be done dynamically.

Usage

bivariateNormal(rho = 0, layout = c(3, 3), lwd = 0.2,
                angle = c(22.5, 67.5, 112.5, 337.5, 157.5, 292.5, 247.5, 202.5),
                col.regions = trellis.par.get("regions")$col, ...)

Arguments

`rho`	Correlation between $x$ and $y$.
`layout, lwd`	Standard lattice arguments.
`angle`	This is used as the `z` component of the `screen` argument to `panel.wireframe`.
`col.regions, ...`	See `wireframe`.

Details

The default setting shows the view as seen from a series of eight angles. To see just a single view, see the example.

Value

"trellis" object.

Note

Based on the galaxy example on pages 204–205 in S \& S-PLUS Trellis Graphics User's Manual, Richard A. Becker and William S. Cleveland (1996), https://www.stat.auckland.ac.nz/~ihaka/courses/120/trellis.user.pdf

Examples

bv8 <- bivariateNormal(.7)  ## all views on one page
bv8
update(bv8[3], layout=c(1,1)) ## one panel
## Not run: 
  if (interactive())
    shiny::runApp(file.path(system.file(package="HH"), "shiny/bivariateNormal")) ## 3D
  if (interactive())
    shiny::runApp(system.file("shiny/bivariateNormalScatterplot", package="HH")) ## scatterplot

## End(Not run)
