plot.resp_surf: Plot the response surface model

Description

Plot the response surface model using a contour plot

Usage

# S3 method for resp_surf
plot(x, xlab = NULL, ylab = NULL, region = TRUE, resolution = 100, ...)

Arguments

x

An object of class resp_surf

xlab

The label for the x axis

ylab

The label for the y axis

region

Logical argument indicating whether regions between contour lines should be colored.

resolution

The resolution of the contour plot. Defaults to 100. higher values produce high-resolution plots but may increase the computation time.

...

Other arguments passed from contourplot function. See contourplot for more details.

Value

An object of class trellis.

# NOT RUN {
library(metan)
# A small toy example

df <- data.frame(
