In gary-au/pt: Computational models for prospect theory and other theories of risky decision making

Description

Plot the utility function.

Usage

plotUtility(my_title, my_title_colour, my_title_font_size, my_x_label, xmin,
  xmax, my_y_label, fun, par, fun_colour, draw_reference_line_flag,
  reference_line_colour, reference_line_style, my_labels, my_label_positions,
  my_label_colours, my_label_font_sizes)

Arguments

my_title	text, the title of the chart.
my_title_colour	text, the title colour.
my_title_font_size	numeric, the title font size.
my_x_label	text, the x-axis label.
xmin	numeric, the xmin on the x-axis.
xmax	numeric, the xmax on the x-axis.
my_y_label	text, the y-axis label.
fun	Utility, an instance of the Utility class.
par	vector, the parameters for the utility function.
fun_colour	text, the colour of the utility function line.
draw_reference_line_flag	logical, a boolean flag determining whether or not to draw a y=x reference line.
reference_line_colour	text, the reference line colour.
reference_line_style	numeric, the reference line style.
my_labels	vector, a vector of text labels to draw.
my_label_positions	list, a list of coordinates for the text labels.
my_label_colours	vector, stores the colours for each text label.
my_label_font_sizes	vector, stores the font size of each text label.

Examples

plotUtility(my_x_label = "objective consequence",
	my_y_label = "subjective value",
	xmin = -10, xmax = 10,
	fun=power_uf,
	par=c(alpha = 0.88, beta = 0.88, lambda = 2.25),
	fun_colour = "purple",
	draw_reference_line_flag = TRUE,
	reference_line_colour = "red",
	reference_line_style = 1)
