laffer: Laffer curve

In R-CoderDotCom/econocharts: Microeconomics and Macroeconomics Charts Made with 'ggplot2'

Description

Creates Laffer curves. The function allows specifying a custom Laffer curve, modifying the maximum X and Y axis values, creating intersections along the values of the Y-axis and the curve and customizing the final output with other arguments.

Usage

laffer(
  curve,
  t,
  xmax,
  ymax,
  pointcol = 1,
  generic = TRUE,
  showmax = TRUE,
  main = NULL,
  sub = NULL,
  xlab = NULL,
  ylab = NULL,
  acol,
  alpha = 0.3,
  bg.col = "white"
)

Arguments

curve	Specify a custom curve (as data.frame). This will override the sample curve.
t	Y-axis values where to create intersections with the Laffer curve.
xmax	Numeric. Allows modifying the maximum X value for the default Laffer curve.
ymax	Numeric. Allows modifying the maximum Y value for the default Laffer curve.
pointcol	Color of the point that represents the optimum point.
generic	Boolean. If TRUE and x is specified, the axis labels shows generic names. If FALSE, the axis labels are the actual data of the axis that corresponds to the intersection points and the optimal point.
showmax	If TRUE, shows the optimal point.
main	Main title of the plot.
sub	Subtitle of the plot.
xlab	Name of the X-axis.
ylab	Name of the Y-axis.
acol	Color of the area of the curve.
alpha	Transparency of the colored area.
bg.col	Background color of the plot.
