addSimplex2Surface {labsimplex}

Adds the simplex movements to a response surface contour

Description

The function complements the contour plot produced by using cntr function. Given a contour plot and a simplex (an object of class smplx) the function adds the simplex movements to the contour plot to illustrate the optimization process and the path that was followed.

Usage

addSimplex2Surface(p, simplex)

Arguments

p

contour plot produced by using cntr function

simplex

simplex object of class smplx. Usually produced using exampleOptimization

Value

a ggplot object with the optimization path over the contour plot provided.

Examples

simplex <- exampleOptimization(surface = exampleSurfaceR2,
                               centroid = c(7, 340),
                               stepsize = c(1.2, 15))
p <- cntr(surface = exampleSurfaceR2)
p <- addSimplex2Surface(p = p, simplex = simplex)
print(p)
