Plots a surface
Plots a surface object in several different ways to give 3-d information e.g. a contour plots, perspective plots.
## 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, ...)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 predictSurface. |
main |
Title for plot. |
type |
type="p" for a perspective/drape plot (see drape.plot), type="I" for an image plot with a legend strip (see image.plot), type="c" draws a contour plot, type="C" is the "I" option but 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 |
