Plot Method for an Object of Class simstatespace

Plot Method for an Object of Class simstatespace

Usage

# S3 method for class 'simstatespace'
plot(x, id = NULL, time = NULL, eta = FALSE, type = "b", ...)

Arguments

x

Object of class simstatespace.

id

Numeric vector. Optional id numbers to plot. If id = NULL, plot all available data.

time

Numeric vector. Optional time points to plot. If time = NULL, plot all available data.

eta

Logical. If eta = TRUE, plot the latent variables. If eta = FALSE, plot the observed variables.

type

Character indicating the type of plotting; actually any of the types as in plot.default().

...

Additional arguments.
