plot: Plotting of "contDist" Objects

Description

Functions for plotting of contDist objects, either directly or as part of contHMM objects.

Usage

"plot"(x, step.size = 0.01, new.plot = TRUE, weight = 1, ...)
"plot"(x, step.size = 0.01, new.plot = TRUE, weight = 1, ...)
"plot"(x, ...)

Arguments

x

Object of class contDist or contHMM.

step.size

Numeric value indicating the distance between points at which the density function is evaluated.

new.plot

If this is TRUE (the default) a new plot is created, otherwise graph of the density function is added to the current plot.

weight

Weighting factor. The density function will be scaled by this factor. This is useful when plotting mixture components.

...

Additional arguments to be passed to plot

Value

These functions are called for their side effect.

Examples

## create two state HMM with t distributions
state.names <- c("one","two")
transition <- c(0.1, 0.02)
location <- c(1, 2)
scale <- c(1, 1)
df <- c(4, 6)
model <- getHMM(list(a=transition, mu=location, sigma=scale, nu=df),
    state.names)
    
## plot emission distributions of HMM
plot(model)

## now plot density functions separately
par(mfrow=c(1,1))
plot(model@emission$one)
plot(model@emission$two, new.plot=FALSE, lty=2)
legend("topleft", legend=states(model), lty=1:2)
