Display Indifference Curves on a standardized ICE Economic Preference Map

Description

Display plots of the Indifference Curves of an ICE Economic Preference Map using the contourplot() and expand.grid() functions from the lattice R-package.

Usage

 ## S3 method for class 'ICEepmap'
plot(x, xygrid = FALSE, ...)

Arguments

Details

If xygrid == FALSE, the default xygrid wiil be a 201 x 201 lattice of equally spaced plotting positions covering the x=DeltaEffe and y=DeltaCost ranges [-10,+10]. This default is: x <- seq(-10, +10, length = 201); y <- x; xygrid <- expand.grid(x = x, y = y)

Value

NULL
