plot.bivden: Plotting a bivariate kernel density estimate object

Description

plot methods for classes "bivden" and "rrs"

Usage

## S3 method for class 'bivden':
plot(x, \dots, display = c("heat", "contour", "persp", "3d"),
 show.WIN = TRUE)
## S3 method for class 'rrs':
plot(x, \dots, display = c("heat", "contour", "persp", "3d"),
 show.WIN = TRUE)

Arguments

An object of class "bivden" resulting from a call to bivariate.density, or an object of class "rss" resulting from a call to risk

...

Additional graphical parameters to be passed to the relevant plot command depending on the value of display.

display

One of four possible character strings indicating the kind of plot desired (see 'Details'). Defaults to "heat".

show.WIN

Boolean. Whether or not to draw the study region as an aesthetic enhancement to the plot of the density/risk surface. Defaults to TRUE.

`Value`

Plots to the relevant graphics device.

`Details`

There are currently four implemented plot types to visualise the estimated density or risk function. "heat" selects a heatplot, "contour" is simply a contour plot and "persp" creates a perspective plot. Selection of "3d" uses functions from the rgl package to open an RGL graphics device and creates a 3-dimensional surface which the user can interact with using the mouse. To use ... to improve the appearance of the four possible plot types "heat", "contour", "persp" and "3d", the reader is highly recommended to consult the relevant documentation in the help pages plot.im, contour, persp and persp3d respectively.
