plot_transition: Plot the transition function of the estimated PSTR model.

In lxylky1688/PSTRM: Panel Smooth Transition Regression Modelling

Description

This function plots the transition function of the estimated PSTR model.

Usage

plot_transition(obj, log_scale = F, size = 1.5, color = "black", ...)

Arguments

obj	an object of the class PSTR returned from some functions in the package. Note that the corresponding PSTR model must be estimated first.
log_scale	specify whether to use log transformation for x-axis.
size	the size of the circle.
color	the color of the circle.
...	expression or strings of names passed to the labs function in ggplot2. The names should be some of "x", "y", "title", "subtitle", and "caption".

Details

The funciton uses some functions in the ggplot2 package and aims to give a quick plot of the transtion function. The user can customize the title, subtitle, caption, x and y labels, for details, read the help file for the labs function in ggplot2.

Value

A ggplot object. The user can plot it simply by print the object.
