p3d function

Three dimensional plotting

Three dimensional plotting of points. Produces a nice-looking 3D scatterplot with greying out of further points giving a visual depth cue

p3d(x, y, z, xlim = NULL, ylim = NULL, zlim = NULL, d0 = 0.2, h = 1, ...)

Arguments

• x,y,z: vector of $x,y,z$ coordinates to be plotted. If x is a matrix, interpret the rows as 3D Cartesian coordinates
• xlim,ylim,zlim: Limits of plot in the $x,y,z$ directions, with default NULL meaning to use range()
• d0: E-folding distance for graying out (depths are standardized to be between 0 and 1)
• h: The hue for the points, with default value of 1 corresponding to red. If NULL, produce black points greying to white
• ...: Further arguments passed to persp() and points()

Returns

Value returned is that given by function trans3d().
