Functions arrows3D
and segments3D
draw arrows and line segments
between pairs of points.
Functions box3D
and border3D
draw boxes between pairs of points.
polygon3D
draws polygons; rect3D
draws rectangles.
The 2D functions arrows2D
, segments2D
, rect2D
and polygon2D
are included
for their side effect of having a color key.

x0, y0, z0 
coordinates of points from which to draw. 
x1, y1, z1 
coordinates of points to which to draw.
For 
x, y, z 
coordinates of the vertices of the polygon.
The polygon will be closed by joining the last point to the first point.
The coordinates can contain missing values ( 
colvar 
The variable used for coloring. It need
not be present, but if specified, it should be a vector of
dimension equal to the coordinates or to the number of polygons.
Values of 
theta, phi 
the angles defining the viewing direction.

col 
Color palette to be used for coloring the arrows or segments
as specified by the 
NAcol 
Colors to be used for 
breaks 
a set of finite numeric breakpoints for the colors; must have one more breakpoint than color and be in increasing order. Unsorted vectors will be sorted, with a warning.
