R: Plot a contour view of a function.

contourview.fun

R Documentation

Plot a contour view of a function.

Description

Plot a contour view of a function.

Usage

  contourview.fun(fun,
    dim = ifelse(is.null(center), 2, length(center)),
    center = NULL, axis = NULL, npoints = 20, nlevels = 10,
    col = "blue", filled = FALSE, mfrow = NULL,
    Xname = NULL, yname = NULL, Xscale = 1, yscale = 1,
    xlim = c(0, 1), ylim = NULL, title = NULL, add = FALSE,
    ...)

Arguments

`fun`	an object of class `"function"`.
`dim`	the dimension of fun arguments.
`center`	optional coordinates (as a list or data frame) of the center of the section view if the model's dimension is > 2.
`axis`	optional matrix of 2-axis combinations to plot, one by row. The value `NULL` leads to all possible combinations i.e. `choose(D, 2)`.
`npoints`	an optional number of points to discretize plot of response surface and uncertainties.
`col`	color for the surface.
`filled`	use filled.contour
`nlevels`	number of contour levels to display.
`mfrow`	an optional list to force `par(mfrow = ...)` call. The default value `NULL` is automatically set for compact view.
`xlim`	a list to give x range for all plots.
`ylim`	an optional list to force y range for all plots.
`Xname`	an optional list of string to overload names for X.
`yname`	an optional string to overload name for y.
`Xscale`	an optional factor to scale X.
`yscale`	an optional factor to scale y.
`title`	an optional overload of main title.
`add`	to print graphics on an existing window.
`...`	further arguments passed to the first call of `plot3d`.

Details

Experimental points are plotted with fading colors. Points that fall in the specified section (if any) have the color specified col_points while points far away from the center have shaded versions of the same color. The amount of fading is determined using the Euclidean distance between the plotted point and center. The variables chosen with their number are to be found in the X slot of the model. Thus they are 'spatial dimensions' but not 'trend variables'.
