## 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
