## S3 method for class 'qdm'
persp(x, col = "gray", zlim = 0:1, phi = 10, theta = -25,
      xlab = "OA1", ylab = "OA2", zlab = "Predictions", ...)

Arguments

x

object of class 'qdm'. See qdm.

col

the color(s) of the surface facets. Transparent colours are ignored. This is recycled to the (nx-1)(ny-1) facets.

zlim

Defaults to zlim=c(0,1) since probabilities are plotted.

theta, phi

angles defining the viewing direction. 'theta' gives the azimuthal direction and 'phi' the colatitude.

xlab, ylab, zlab

titles for the axes. N.B. These must be character strings; expressions are not accepted. Numbers will be coerced to character strings.

...

additional graphical parameters (see 'par').
