Plots highest density regions continuously over some conditioned variable.

Source: R/plotcde.R
plot.hdrcde.Rd

Plots highest density regions continuously over some conditioned variable.

Usage

# S3 method for class 'hdrcde'
plot(
  x,
  plot.modes = TRUE,
  mden,
  threshold = 0.05,
  xlim,
  ylim,
  xlab,
  ylab,
  border = TRUE,
  font = 1,
  cex = 1,
  ...
)

Arguments

x

Output from hdr.cde().

plot.modes

Should modes be plotted as well as HDRs?

mden

Marginal density in the x direction. When small, the HDRs won't be plotted. Default is uniform so all HDRs are plotted.

threshold

Threshold for margin density. HDRs are not plotted if the margin density mden is lower than this value.

xlim

Limits for x-axis.

ylim

Limits for y-axis.

xlab

Label for x-axis.

ylab

Label for y-axis.

border

Show border of polygons

font

Font to be used in plot.

cex

Size of characters.

...

Other arguments passed to plotting functions.

Value

None.

Examples

faithful.cde <- cde(faithful$waiting, faithful$eruptions)
faithful.hdr <- hdr.cde(faithful.cde, prob = c(0.50, 0.95), plot = FALSE)
plot(faithful.hdr, xlab = "Waiting time", ylab = "Duration time")
