plot3D function

Surface plot of two-dimensional test function.

plot3D(x, length.out = 100L, package = "plot3D", ...)

Arguments

• x: [smoof_function]

  Two-dimensional snoof function.

• length.out: [integer(1)]

  Determines the smoothness of the grid. The higher the value, the smoother the function landscape looks like. However, you should avoid setting this parameter to high, since with the contour option set to TRUE

  the drawing can take quite a lot of time. Default is 100.

• package: [character(1)]

  String describing the package to use for 3D visualization. At the moment plot3D (package plot3D) and plotly (package plotly) are supported. The latter opens a highly interactive plot in a web brower and is thus suited well to explore a function by hand. Default is plot3D .

• ...: [any]

  Furhter parameters passed to method used for visualization (which is determined by the package argument.

Examples

library(plot3D)
fn = makeRastriginFunction(dimensions = 2L)
## Not run:

# use the plot3D::persp3D method (default behaviour)
plot3D(fn)
plot3D(fn, contour = TRUE)
plot3D(fn, image = TRUE, phi = 30)

# use plotly::plot_ly for interactive plot
plot3D(fn, package = "plotly")
## End(Not run)
