plot.surface: Plots a surface

Description

Plots a surface object in several different ways to give 3-d information e.g. a contour plots, perspective plots.

Usage

## S3 method for class 'surface':
plot(x, main = NULL, type = "C", zlab = NULL, xlab = NULL,
    ylab = NULL, levels = NULL, zlim = NULL, graphics.reset = NULL,
     labcex = 0.6, add.legend=TRUE, ...)

Arguments

x

A surface object. At the minimum a list with components x,y and z in the same form as the input list for the standard contour, persp or image functions. This can also be an object from predict.surface.

main

Title for plot.

type

type="p" for a perspective/drape plot, type="I" for an image plot with a legend strip (see image.plot). type="C" is the "I" option with contours lines added. type="b" gives both "p" and "C" as a 2X1 panel

zlab

z-axes label

xlab

x-axes label

ylab

y-axes labels

levels

Vector of levels to be passed to contour function.

graphics.reset

Reset to original graphics parameters after function plotting. Default is to reset if type ="b" but not for the single plot options.

zlim

Sets z limits on perspective plot.

labcex

Label sizes for axis labeling etc.

add.legend

If TRUE adds a legend to the draped perspective plot

...

Other graphical parameters that are passed along to either drape.persp or image.plot

Examples

fit<- Tps( BD[,1:4], BD$lnya) # fit surface to data 

# surface of variables 2 and 3 
#    holding 1 and 4 fixed at their median levels
 out.p<-predict.surface(fit, xy=c(2,3))  
 plot.surface(out.p, type="C") # surface plot
