  ...,
  ncurves = 1,
  xmax,
  ymax,
  type = "normal",
  x,
  pointcol = 1,
  curve_names = TRUE,
  names,
  linecol,

  bg.col = "white"
)

Arguments

...

Specify the curve or curves separated by commas (as data.frame) you want to display in the graph. This will override the sample curve.

ncurves

If ... is not specified, is the number of indifference curves to be generated based on the sample data.

xmax

Numeric. Allows modifying the maximum X value for the default indifference function.

ymax

Numeric. Allows modifying the maximum Y value for the default indifference function.

type

Possible values are "normal, for a normal indifference function, "psubs" for perfect substitute and "pcom" for perfect complements.

x

Y-axis values where to create intersections with the indifference curves.

pointcol

If x is specified, is the color of the points that represents the intersections.

curve_names

Boolean. If TRUE, the function adds default names to each.

names

If curve_names = TRUE are custom names for the curves.

linecol

Line color of the curves.

labels

If x is specified are the labels for the intersection points.

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.

geom

Possible values are "text" to display the labels of the intersection points with text and "label" to show them with labels.

geomcol

Color of the labels of the intersection points.

geomfill

If geom = "label" is the background color of the label.

main

Main title of the plot.

sub

Subtitle of the plot.

xlab

Name of the X-axis.

ylab

Name of the Y-axis.

bg.col

Background color of the plot.
