plot.surface {fields} | R Documentation |
Plots a surface object in several different ways to give 3-d information e.g. a contour plots, perspective plots.
plot.surface(x, main = NULL, type = "b", zlab = NULL, xlab = NULL, ylab = NULL, levels = NULL, zlim = NULL, graphics.reset = NULL, labcex = 0.6, ...)
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 plot, type="c" for a contour plot and type="b" for both (default). type="I" for an image plot with a legend strip (see image.plot). type="C" is the "I" option with contours lines added. |
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. |
... |
Other graphical parameters that are passed along to either persp, contour or image. |
