This vectoriation is a good idea! I agree that implementing it in the 
same function
as for only one polygon is much preferable, w.r.t. coding a specific 
xrpoly*s*()
function as it has been done for most of other functions plotting 
geometrical
shapes : xrect > xrects, etc..

Since a SEP is running, here are some ideas of other possible developments
for new  features:
- why not *vectorizing also n, r and theta*? (with default = scalar)
- *filling = filling_color* (optional): to fill the polygon(s) with 
respective
     colors (vector of indices in the color_map).
     a color<0 means that the line (border) must not be plotted.
- *symbol=[symbol_numbers, symbol_sizes]*: to put a symbol on the angles
   (the same on all angles, but may be different from a polygon to 
another one
   => vectorized = mx2 matrix).
- *isoview=%t* option, to force the targetted axes to be isometric to show
    a truly regular polygonal (see the present mis-shaped sample in help 
xrpoly)
- *showAll=%t* option: => enlarge axes bounds up to the external bounds of
    generated polygons
- returning the *vector of created handles*

xrpoly([0.5 0.5], 12, 0.4, symbol=[14, 8], filling=-color("cyan"), 
isoview=%t)
// would display (for a single polygon)



Hoping reading you soon
Samuel
